## Key facts
- Make: Ferrari
- Model: 328 GTB / GTS
- Generation: 328
- Factory code: Tipo F106 MB / F106 MS
- Years: 1985 to 1989
- Body styles: 2-door Berlinetta (fixed-roof coupe, GTB), 2-door Spider/targa with lift-out roof panel and fixed rear buttresses (GTS)
- Engines: 3,185 cc Tipo F105 CB 000 transverse 90-degree V8, DOHC per bank, four valves per cylinder, Bosch K-Jetronic mechanical injection, Marelli MED 806 A ignition, 9.8:1 compression, 270 hp at 7,000 rpm and 224 lb-ft at 5,500 rpm (European specification); 3,185 cc F105 C tipo 040 catalyzed variant for the United States, Japan and Australia, 9.2:1 compression, 260 hp at 7,000 rpm SAE net and approximately 213.5 lb-ft at 5,500 rpm; 3,185 cc F105 C tipo 046 catalyzed variant for Switzerland and Sweden from spring 1987, KE3-Jetronic injection, 255 hp at 6,750 rpm SAE net and approximately 202 lb-ft at 5,500 rpm
- Production total: 7,412
- Production notes: The 328 is an unusually well-behaved car to count. Ferrari's own model record states 1,344 GTBs, chassis 58735 to 83017; the GTS figure of 6,068, chassis 59301 to 83136, is given identically by Wikipedia, Conceptcarz, the Ferrarista buying guide and three separate RM Sotheby's catalogue entries consulted here. The two add to 7,412, and no source consulted disagreed with either component, so a total is asserted rather than withheld. The split is the interesting part: at roughly four and a half GTS to every GTB, the closed car - normally the volume body in any range - is the rare one, which inverts the scarcity logic buyers usually apply.

Right-hand drive is where the counting gets soft. Supercar Nostalgia gives 130 right-hand-drive GTBs and 542 right-hand-drive GTSs without qualifying the market. The Ferrarista guide gives the same two numbers but describes both as UK cars, and adds a further 152 right-hand-drive GTSs delivered to Australia, along with 135 GTBs for the United States. Whether 542 is the whole right-hand-drive GTS figure or only the British share is not resolved by any source read here, so the numbers are reported as quoted rather than summed.

Two scope notes. The Ferrarista guide records a single factory convertible, chassis 49453, built during development and never approved for production; that chassis number sits well below the 328 series range and no second source consulted confirms it, so it is reported and not counted. Separately, the 1,991 cc GTB Turbo and GTS Turbo built for the Italian market between 1986 and 1989 - 308 and 828 cars respectively per Wikipedia - wear the 328's restyled bodywork but are two-liter turbocharged cars built to sit under Italy's punitive VAT threshold. They are not 328s and are not included in the 7,412.

## Summary
The Ferrari 328 (1985-1989) is the last and most developed form of the transverse-V8 line that began with the 308 GTB in 1975, and it is best read as a refinement of that car rather than a replacement for it. Pininfarina rounded the nose, deleted the louvres behind the headlight pods and replaced the 308's black rubber-faced bumpers with body-colored moldings blended into the valances, aligning the car visually with the Mondial 3.2 and Testarossa. Underneath, the quattrovalvole V8 grew from 2,927 cc to 3,185 cc for 270 hp in European tune, the track was widened, the steering rack was quickened to 288 GTO specification and the bodyshell was galvanized. From February 1988 anti-lock braking became available, bringing a revised front geometry with negative wheel offset and convex wheels in place of the earlier concave pattern. Buyers overwhelmingly chose the targa: 6,068 GTS against 1,344 GTB. Among the older mid-engined Ferrari V8s the 328 carries the strongest reputation for dependability, helped considerably by a cam-belt service that does not require the engine to come out.

## Notable variants
- 328 GTB: The fixed-roof berlinetta: 1,344 built against 6,068 GTS, chassis 58735 to 83017. Stiffer, quieter and considerably rarer, and the only body style in the range carrying a scarcity premium.
- 328 GTS: The targa, with a lift-out roof panel between fixed buttresses, and the car most buyers actually bought: 6,068 built, chassis 59301 to 83136. About ten kilograms heavier than the GTB and the default way into the model.
- 328 with ABS (from February 1988, chassis 76626): The mid-life car. Anti-lock braking required a reworked front geometry with negative wheel offset, which in turn required convex 16-inch wheels in place of the concave pattern. Door-mirror Cavallino badges and twin hood catches identify them.
- 328 (United States specification): Catalysed 260 hp SAE net on 9.2:1 compression, curb weight quoted near 3,142 lb against roughly 2,784 lb for a European GTB. No ABS through the 1988 'MY 1988 1/2' season, and only from model year 1989.
- 328 (Switzerland and Sweden, tipo 046): From spring 1987, a catalyzed specification using KE3-Jetronic and quoted at 255 hp at 6,750 rpm. The lowest-output 328, and easy to mistake for a standard European car on paperwork alone.
- 328 (right-hand drive): Quoted at 130 GTBs and 542 GTSs, with a further 152 right-hand-drive GTSs said to have gone to Australia. A right-hand-drive GTB is a car in the low hundreds worldwide, and priced accordingly in Britain.
- GTB Turbo / GTS Turbo (Italian market): Not a 328. A 1,991 cc IHI-turbocharged two-valve V8 of 251 hp in the 328's bodyshell, built 1986-1989 to sit under Italy's 2.0-liter VAT threshold. Counted separately, at 308 GTB Turbos and 828 GTS Turbos.

## History

### Refinement, Not Replacement
By 1985 the transverse-V8 Ferrari was a decade old. The 308 GTB had arrived in 1975, acquired fuel injection, then four valves per cylinder in 1982, and had quietly become the company's volume model. Rather than start again, Maranello enlarged the engine, tidied the body and let the design see out the decade. Ferrari's own record has the 328 GTB shown at the Frankfurt Salon in the autumn of 1985 and replaced by the 348 tb in the autumn of 1989 - four model years, and the last of the line before the 348 turned the engine through ninety degrees and changed the character of the car entirely. The 328 is therefore not a new idea but a finished one, and almost every difference from the 308 is a correction rather than an invention.

### The 3.2-Liter Quattrovalvole
The engine is the clearest of those corrections. The quattrovalvole V8 went from 2,927 cc to 3,185 cc, bore rising from 81 mm to 3.3 in (83 mm) and stroke from 71 mm to 2.9 in (73.6 mm), with compression lifted from 9.2:1 to 9.8:1 on European cars and from 8.6:1 to 9.2:1 on catalyzed American ones. Ferrari's type reference is F 105 CB 000. Bosch K-Jetronic mechanical injection was carried over and Marelli MED 806 A electronic ignition fitted. European output rose to 270 hp at 7,000 rpm against the quattrovalvole's 240, with 224 lb-ft at 5,500 rpm; the American car, breathing through catalysts, was quoted at 260 hp and about 213.5 lb-ft, and from the spring of 1987 a further tipo 046 specification with KE3-Jetronic served Switzerland and Sweden at 255 hp. Thirty horsepower is not transformative, and peak power was never the point: the gain sits in the mid-range, which is exactly where the 308 had always felt thin.

### Pininfarina's Second Pass
The body changes are subtle in photographs and obvious in the metal. The nose was rounded and the wedge softened, the louvres behind the headlight pods deleted, the radiator exhaust louvre enlarged and the tail restyled. The most consequential change was the bumpers, which became body-colored moldings blended into the front and rear valances in place of the 308's black rubber-faced items - done deliberately so that the eight-cylinder cars, the Mondial 3.2 among them, read as one family. Beneath the skin the F106 tubular frame continued under new numbering, the track was widened by 0.98 in (25 mm) at the front and 0.20 in (5 mm) at the rear, Koni dampers were fitted throughout, the rack was quickened to the ratio used on the 288 GTO, and the bodyshell was galvanized. That last item has done more for survival rates than anything else on the list.

### February 1988: ABS, Geometry and Convex Wheels
The mid-life change arrived in February 1988, from chassis 76626. Anti-lock braking was not a bolt-on: the front suspension geometry was reworked to a negative wheel offset and the dampers retuned to reduce squat and dive, and the new offset required new wheels, the concave 16-inch pattern giving way to the convex design shared with the Mondial 3.2. Revised cars carry a Cavallino Rampante on each door mirror and twin hood catches, and are commonly described as MY 1988 1/2. Whether ABS was optional or standard depends on which source is consulted and probably on the market; American cars went without it entirely through 1988 and received it only for model year 1989. Collectors read the change in both directions - the later car is the better-developed one, the earlier the purer - and the market has never settled the argument.

### Targas, Right-Hand Drive and the Afterlife
Buyers voted for the removable roof by a margin that still shapes the market: 6,068 GTS against 1,344 GTB, about four and a half to one. Right-hand-drive numbers are smaller again, 130 GTBs and 542 GTSs being the figures usually quoted, with a further 152 right-hand-drive GTSs said to have gone to Australia. Production ended in 1989 and the 348 took over. What the 328 acquired afterwards was a reputation none of its successors managed: among the older mid-engined V8s it is the car specialists describe as dependable, in large part because its cam-belt service can be carried out with the engine in the car - a sentence that cannot be written about the 355 that followed.

## What to look for

Belt-service history is the dominant document. The interval is quoted at five years or 30,000 miles, and unlike most later mid-engined Ferraris the job is done with the engine in the car, so the consequence of a lapse is measured in engine damage rather than in an unpayable bill. Dated invoices naming the tensioner and idler bearings, not just the belts, are what separate a documented car from an asserted one; a car whose last belt is undated should be costed as needing one immediately. Establish the specification before the condition. Chassis 76626 and February 1988 divide the run: ABS cars carry convex wheels, negative-offset front geometry, twin hood catches and Cavallino Rampante badges on the door mirrors, and a car advertised as a late one wearing concave wheels needs explaining. Confirm which market the engine was built for - European 270 hp, catalyzed American 260 hp, or the Swiss and Swedish tipo 046 at 255 hp - since the paperwork does not always say. The shell is galvanized but not immune: check sills, the front of the rear arches, the battery tray and the trunk floor, and on a GTS the targa panel seals and the channel the panel sits in. Matching engine and gearbox numbers and a Ferrari Classiche certificate both show up in the strongest auction results. On an American car, confirm the 1989 NHTSA recall on the front lower suspension arm forks was carried out. Finally, weigh a car that has sat: K-Jetronic systems and fuel lines dislike long storage more than they dislike use.

## Common problems

The mechanical package is the least troublesome of the older mid-engined V8s, and specialists say so plainly - Continental AutoSports' technical manager described the 328 as one of the most reliable models Ferrari ever built, provided it is maintained. Oil weeps are normal rather than alarming: cam covers, cam seals and the gearshift shaft seal are the usual sources, and a light drip from the sump area is expected. Electrical faults are the more common irritation, with arcing at the fuse-box terminals a known pattern and climate-control switches failing at the illumination first, which means replacing the whole switch. K-Jetronic is mechanically robust but resents standing, and cars recommissioned after long storage frequently need fuel lines, an accumulator or a warm-up regulator. The scheduled work is where the money goes. The belt service runs to roughly $3,500 to $5,900 at American independents by owners' own accounts, with a UK specialist quoted nearer $2,100 for comparable work; dealer menu pricing for a 308/328 major service starts at $8,250 and rises to $12,999 where valve covers, cam seals and shim adjustment are included. Valves want checking at 15,000-mile intervals and gearbox oil every two years in a car covering meaningful distance. On American cars, NHTSA campaign 89V111000 of May 1989 replaced the four front lower suspension arm forks with thicker items after they were found liable to deform following a substantial impact.

## Market notes

As of August 2026, classic.com's Market Benchmark for the 328 GTB stands at approximately $173,011 on a rising trend, and for the 328 GTS at approximately $115,000 - $115,363 on the model landing page and $115,108 on the GTS sub-market page, also rising. The GTB premium is roughly fifty per cent, which is the scarcity ratio expressing itself directly. The lowest sale classic.com tracks is $47,250, a 1988 GTS in April 2023; current asking prices on the site span roughly $112,000 to $290,000. Auction evidence sits above the benchmarks and is dominated by mileage. RM Sotheby's sold a 1988 GTB from the Longhorn Collection, non-ABS and showing 8,380 miles, for $212,800 at Arizona in 2026; a 1989 GTB with 8,286 miles and Swiss delivery made EUR 120,750 at Paris in 2024; a 1989 GTS with 17,657 miles and a 2023 belt change made EUR 92,000 at Villa Erba in 2023; and a Classiche-certified 1989 GTS showing 1,491 miles made $235,200 at Miami in 2022. All four are 'Sold for' figures and therefore include buyer's premium, not hammer. Prices quoted here are as of August 2026.

## Value trajectory

The 328 spent most of its life as the cheap way into a mid-engined Ferrari and stopped being that somewhere around the middle of the last decade, when the analogue, manual, pre-electronics cohort re-rated as a group and the 328 went with it. Its position now is settled rather than speculative: as of August 2026 classic.com shows both body styles trending upward, with the GTB benchmark near $173,011 and the GTS near $115,000, and the gap between them tracking the four-and-a-half-to-one production ratio more faithfully than it did ten years ago. The more instructive spread is within each body style rather than between them. A 1989 GTS with 17,657 miles made EUR 92,000 at Villa Erba in 2023, while a Classiche-certified 1989 GTS showing 1,491 miles made $235,200 at Miami in 2022 - the same car in every respect that matters mechanically, separated by an odometer and a folder of invoices. Since the 328's whole case rests on being the dependable one, documentation of the belt service is the value factor that behaves least like a fashion, and the widening distance between recorded and unrecorded cars is the clearest trend in the model.
