300ZX (Z32 (fourth-generation Z))

Drawn in Three Dimensions Nissan management approved the Z32's final form on 1 October 1986, from work by Isao Sono and Toshio Yamashita, and developed the body with CAD software running on a Cray supercomputer, among the first production cars designed that way rather than modelled and tunnelled. It abandoned the Z31's pop-up lamps for fixed faired units and a wide, low, cab-forward stance, though not for slipperiness alone: the drag coefficient came out at 0.31, marginally worse than the car it replaced. Japan saw it in July 1989, twenty years after the original S30, and America received it as a 1990 model.

One Engine, Three Published Outputs The 2,960 cc V6 came two ways. The VG30DE was a naturally aspirated DOHC 24-valve unit with variable intake cam timing and coil-on-plug ignition, quoted at 222 bhp for the United States. The VG30DETT added two parallel Garrett turbochargers, two intercoolers, oil-cooled pistons and a lower 8.5:1 compression ratio, and was rated at 300 bhp and 283 lb-ft for export. In Japan the same engine was advertised at 280 PS. That figure was not a mechanical fact but a commercial one: at the end of 1988 the major Japanese manufacturers settled on a voluntary ceiling of 280 PS for domestic advertising, a restraint that held until 2004, and the Z32 was the first car marketed under it. Continental European cars, tuned for different emissions rules, were quoted at 228 PS. One engine, three numbers, and only one of them describes anything mechanical.

Chassis Ambition and Its Price Underneath was multi-link suspension front and rear, ventilated discs with opposed four-piston aluminium calipers at both ends, two-mode adjustable damping on turbo cars, and Super HICAS rear-wheel steering, which steers the rear wheels briefly out of phase with the fronts to rotate the car into a corner, then brings them into phase to settle it; actuation was hydraulic until 1993 and electric from 1994. All of it had to be packaged under a low bonnet line, and the consequence is the defining ownership fact about the car: there is effectively no free space in the engine bay. The camshaft belt is an interference design due every 60,000 miles or 48 months and takes around five hours simply to reach. Replacing injectors or resealing a cam cover means removing the upper intake plenum. Jobs that are an hour on other cars are a day here, and that arithmetic has governed how these cars have been maintained, or not, for thirty years.

Roofs, a Convertible, and the 1994 Revisions Every Z32 initially carried T-bar roof panels; a fixed-roof slicktop two-seater followed, and a longer-wheelbase 2+2 sat on 2,570 mm against the two-seater's 2,451 mm. A convertible was announced in August 1992 and sold in America from 1993, naturally aspirated only. The 1994 model year brought the most visible revision of the run: a taller pedestal-type rear spoiler, a passenger airbag as standard, seatbelt anchorages moved from the doors to the pillars, keyless entry, and the switch of Super HICAS to electric actuation.

Daytona, Le Mans, and the Retreat from America In 1994 Clayton Cunningham Racing's 300ZX Turbo won the Daytona 24 Hours outright from the GTS class and took the IMSA GTS class at Le Mans with fifth overall for Steve Millen, Johnny O'Connell and John Morton. The showroom story ran the other way. American volume fell from around 39,000 cars in 1990 to under 3,000 in 1996 as the yen strengthened, buyers moved to sport utilities and the price climbed: a 1990 Turbo listed near $33,000, a 1996 Turbo at $45,422. Nissan withdrew the Z from the United States after 1996, marking the last 300 cars as a Commemorative Edition, and did not return until the 350Z of 2003. In Japan the Fairlady Z carried on quietly until 2000.

Heat is the root of most of it. The engine bay runs hot and packs tightly, and over three decades that has degraded wiring looms, vacuum lines and connectors, with early cars worst affected. The camshaft belt is an interference design: a failure destroys valves and pistons, and reaching it takes about five hours before any parts are fitted. Owner accounts put the full belt package at roughly $450 in Nissan parts and eight to nine hours of dealer labour, with factory turbocharger seals typically weeping from 60,000 to 80,000 miles and a complete turbo replacement quoted at 15.7 hours plus around $2,400 in parts; one long-term owner budgets $3,000 a year beyond fuel, oil and insurance. Fuel injectors and their hoses leak with age, and replacing them means removing the upper plenum. Ignition coils and the ignition power transistor unit fail, often announced by a light rapid ticking. Alternators fail; pre-1991 master cylinders leak; early variable cam timing springs weaken; automatic transmissions overheat; front tension-rod bushings perish; T-top seals let water in and corrode the seat rails. NHTSA's database returns no recall campaigns at all for the 1990-1996 300ZX; the one campaign it holds for the nameplate, 95I006000 of January 1995, covering leaking fuel injectors and hoses, is filed against the earlier Z31 model years.

Documented cam-belt history comes first. The interval is 60,000 miles or 48 months, the engine is an interference design, and the job is deep enough that owners defer it; a car without paperwork should be costed as though it is due, along with the water pump, tensioner, cam and crank seals and coolant hoses done at the same time. Ask whether the upper plenum has ever been off and whether a coolant bypass was fitted while it was, since that one modification makes every later job cheaper. Heat is the second theme: baked wiring insulation, brittle vacuum lines and crumbling connectors, worst on early cars. On turbo models watch for smoke on overrun pointing to turbo seals, which typically weep between 60,000 and 80,000 miles. Check that Super HICAS still functions rather than having been locked out with an eliminator bar. Bodily, T-top cars leak and rot their seat rails, and British cars add sill corrosion in a triple-layer structure that needs a specialist, plus rear arches; pre-1991 master cylinders leak and front tension-rod bushings perish. Establish the body exactly - 2+0 or 2+2, T-top or slicktop, turbo or naturally aspirated - because the value spread between them is wider than the condition spread within any one of them. Modified turbo cars are the norm rather than the exception, and standard, unopened examples carry the premium. On a Commemorative Edition, the number and its certificate are the car.

As of August 2026, classic.com's benchmark for the twin-turbo Z32 stands at $28,055 against an average recorded sale of $29,778, with tracked results running from $4,500 for a 1992 car in November 2022 to $52,990 for a 1993 car in August 2026, and the trend arrow pointing down. The naturally aspirated car sits well below it on the same date, at a $13,103 benchmark and a $15,551 average, its lowest tracked result $3,600 in October 2025, also trending down. Japanese-market Fairlady Z imports are tracked separately and lower again: an $11,383 benchmark and a $12,621 average as of August 2026, from $5,350 for a 1990 2+2 in March 2026 to $27,000 for a 1991 car in July 2026. Ordinary transactions are unremarkable - a modified 31,000-mile 1993 Turbo sold for $25,300 at Mecum Kissimmee on 9 January 2025 - and the headline results belong to preservation cars rather than to the model. A 1996 Commemorative Edition, number 300 of 300, showing around 530 miles and previously displayed at the Petersen Automotive Museum, made $90,100 in 2017 against a 1996 Turbo list price of $45,422; a 920-mile car had made $69,900 the year before. British guidance from Hagerty UK's buying guide, read in August 2026, put sound cars needing work near £12,500, documented original UK manual cars near £20,000 and the best turbos above £40,000, with naturally aspirated cars roughly 30 per cent behind.
