- Production total: 237,287
- Production notes: The roadster total is one of the few R107 figures every source consulted here agrees on: 237,287 cars between 1971 and August 1989, stated by Mercedes-Benz's archive, Wikipedia, the mb107.com tables, the SLSHOP and Classic Trim Parts alike. The C107 SLC coupe adds 62,888 cars built between late 1971 and September 1981, giving a 107-series total of 300,175 - although the SLSHOP's fifty-facts piece prints 300,174, a one-car difference that reads as a transcription slip rather than a disagreement.

The mb107.com breakdown runs 350 SL 15,304; 280 SL 25,436; 450 SL 66,298; 380 SL 53,200; 500 SL 11,812; 300 SL 13,742; 420 SL 2,148; 560 SL 49,347. On the coupe side, 350 SLC 13,925; 280 SLC 10,666; 450 SLC 31,739; 380 SLC 3,789; and one line reading '500 SLC 1980-81, 2,769'. That entry is where the figures come apart. Wikipedia and Classic & Sports Car both split the five-liter coupes into 1,636 badged 450 SLC 5.0 and 1,133 badged 500 SLC, which sums to exactly 2,769. The mb107.com table appears to fold the earlier homologation cars into the 500 SLC line rather than to count differently, but no source consulted here says so, and both readings are recorded.

Classic Trim Parts publishes a year-by-year roadster table reconciling to 237,287: three pre-production cars in 1970, a trough of 6,964 in 1974 after the oil crisis, a peak of 20,314 in 1986 - the R107's best year came in its sixteenth - and 7,866 in the final part-year of 1989. Roughly two thirds of production went to North America, an estimate of about 156,000 cars that several sources repeat and none breaks down by year. The SLSHOP dates the last car to 4 August 1989 and describes it as a 500 SL in Astral Silver.

## Summary
The Mercedes-Benz SL of the 107 series replaced the W113 Pagoda in spring 1971 and stayed in production until August 1989 - eighteen years, an internal record for the marque. It was the first SL with a V8 and the first to carry the factory's R prefix rather than W. Where the Pagoda had been light, upright and spare, the R107 was longer, heavier and aimed squarely at North America, which took roughly two thirds of the 237,287 roadsters built. The engine ladder ran from a 2.8-liter twin-cam six through 3.5, 3.8, 4.2, 4.5, 5.0 and finally 5.6 liters of V8, with American cars federalized to sealed-beam headlamps, extended impact bumpers and emissions calibrations that cost them much of the European output. A stretched four-seat coupe, the C107 SLC, ran alongside to September 1981 and gave Mercedes an improbable World Rally Championship winner. Eighteen years of running changes mean the market now sorts these cars by year, color and equipment as much as by badge.

## Notable variants
- 350 SL (1971-1980): The launch car and first V8 SL, 15,304 built, 197 hp on D-Jetronic then K-Jetronic from about December 1975. Chrome bumpers and the pre-1980 cabin make it the least diluted of the run.
- 450 SL (1972-1980): The best-seller at 66,298 and the R107 most Americans bought. The 4,520 cc M117 reached the United States in low-compression export form, and its rated output fell through the decade as emissions hardware accumulated.

- 380 SL (1980-1985): 53,200 built, and the variant with a specific caveat: 1981-1983 cars left the factory with a single-row timing chain, replaced by a double-row design for 1984. Also the weakest North American roadster at 155-157 hp.
- 500 SL (1980-1989): 11,812 built and never sold new in the United States. Wikipedia rates it the fastest production R107, quicker than the larger-engined 560 SL, at 7.4 seconds to 60 mph.
- 560 SL (1985-1989): 49,347 built for North America, Japan and Australia only, with limited-slip differential, ABS and a driver's airbag standard. The variant the current American market treats as the default R107.
- 420 SL (1985-1989): European-market V8 replacing the 380 SL and the rarest R107 roadster at 2,148 cars, with the same 215 hp from 4.2 liters rather than 3.8.
- 450 SLC 5.0 and 500 SLC (C107, 1977-1981): Homologation coupes with an all-aluminum five-liter V8 and alloy opening panels, built for Group 2 and Group 4 rallying. The works cars finished 1-2-3-4 on the 1979 Bandama Rally.

## History

### From Pagoda to Grand Tourer
The 107 series was approved by the Mercedes-Benz board on 18 June 1968 and shown in spring 1971, replacing a W113 in production since January 1968. The change of character was deliberate. The Pagoda had been a light, upright six-cylinder car; the R107 was the first SL with a V8, the first to carry the factory's R prefix rather than W, and in United States specification close to 772 lb heavier. The engineering case rested on Bela Barenyi's crumple-zone work: a rigid passenger cell, A-pillars and screen surround about fifty per cent stronger than before and bonded in for stiffness, the fuel tank moved above the rear axle out of the collision zone, a padded dash with recessed switchgear, and large ribbed tail lamps shaped to shed road dirt and stay visible. What the SL had been was a sports car; what it became was a grand tourer with a hardtop.

### The Engine Ladder
No other Mercedes passenger car carried so many powertrains under one body. The 350 SL launched with a 3.5-liter M116 V8 at 197 hp. A 4,520 cc M117 followed for export, badged 450 SL from 1973 and by far the best-seller at 66,298 cars. The oil crises brought the 2.8-liter M110 twin-cam six in July 1974. March 1980 brought the first substantial update: the alloy-block 380 SL replaced the 350 SL after nine years, the 500 SL replaced the 450, the three-speed automatic gave way to a four-speed, the hardtop became standard and ABS appeared on the options list. September 1985 brought the second: a 3.0-liter M103 six revived the 300 SL name after twenty-two years, the 420 SL replaced the 380 SL in Europe, the 560 SL arrived for export markets, and the front axle and brakes were reworked.

### Federalizing the SL
North America took about two thirds of production, and the American cars are a distinct machine. Four round sealed-beam headlamps replaced the European composite units. From 1974 the bumpers grew by roughly 8.0 in (203 mm) at each end to meet the NHTSA five-mile-per-hour impact standard, and Mercedes kept them until 1989 even after the requirement was relaxed in 1981. Emissions hardware did the rest: the early 450 SL's 192 hp SAE fell away through the decade, and the 380 SL that followed made 155 to 157 hp against 215 hp for the identical European car - Wikipedia records 9.3 seconds to 60 mph, Sports Car Market 11.5. Only with the 560 SL of 1986, sold in North America, Japan and Australia but not Europe, did American buyers get the biggest engine in the range, and even then the European 500 SL remained the faster car.

### The SLC and an Improbable Rally Car
From late 1971 the roadster was joined by the C107 SLC, a four-seat fixed-roof coupe on a wheelbase stretched 14.2 in (360 mm), with pillarless side glass and louvred rear quarter windows. It is the only time Mercedes built its S-Class coupe on a stretched SL platform, and it ended in September 1981 after 62,888 cars when the W126-based SEC took over. Its afterlife was strange. Mercedes took the SLC rallying, with an all-aluminum five-liter V8 and alloy opening panels, homologated by building 1,636 road-going 450 SLC 5.0s from September 1977. The works cars took the top five places on the 1978 Vuelta a la America del Sud and finished 1-2-3-4 on the 1979 Bandama Rally in the Ivory Coast - the first World Rally Championship win for a V8 and for an automatic.

### Eighteen Years, One Silhouette
Because the body barely changed, the differences that matter are underneath and inside: D-Jetronic to K-Jetronic to KE-Jetronic, three speeds to four, better steel from about 1976, cavity wax from 1980, galvanized components from 1986, and a 1986 front air dam that cut front-end lift by around thirty per cent. Color tells the same story - the SLSHOP counts over a hundred factory shades, five of which ran the whole eighteen years, while Mimosa Yellow, Apricot Orange and Cayenne Orange lasted a single season each. The last car left Sindelfingen in August 1989 and the R129 took over.

## What to look for

Corrosion first, and in the places the R107 hides it. The Car Classic guide lists sills and lower skirts, the panel above the headlamps, hood, doors, boot, floors, wheel arches - rear especially - front subframe and wishbones. Hagerty's UK guide adds the screen surround and bulkhead, and notes the bumpers rot from behind, so look behind them rather than at them. Protection improved over the run - better steel from about 1976, cavity wax from 1980, galvanized components from 1986 - which is one practical reason late cars sell for more than early ones. On V8 cars check the front subframe for cracking and listen for chain rattle on start-up; Car Classic treats corrosion, subframe cracking and chain noise as three reasons to walk away rather than negotiate. Establish which timing chain a 380 is running, since 1981-1983 cars left the factory with the single-row design and many but not all have since been converted. Both roofs matter. The steel hardtop should latch and release without force and its chrome should be intact; a car sold without one is a car that needs one found. Fabric hoods shrink in storage, so check the front mounts engage and that the seals are not letting damp into the footwells. Inside, the checked cloth trim is scarce and hard to match, dashboard tops crack in sun, and air conditioning repairs can need the interior out.

## Common problems

The 3,839 cc M116 fitted to 1981-1983 cars used a single-row timing chain that stretched and, in service, broke. Mercedes redesigned the engine around a double-row chain for 1984, and Wikipedia records that failures on affected cars were rectified free of charge at the time; Sports Car Market put a retrofit conversion at around $3,000. This matters because these are interference engines: Pelican Parts is explicit that a skipped tooth is worth twenty degrees of crankshaft rotation and will almost certainly put pistons into valves. Chain stretch is read at the crankshaft timing indicator, with the caveat that the reading can be out by up to three degrees, and the plastic upper guide rails are the more common actual failure, a broken rail jamming against the cam sprocket. Chains are treated as a 100,000-mile item across the V8 range, not only on the 380. Beyond that the engines have a good reputation: Hagerty's UK guide calls them all very reliable, with noisy tappets the usual V8 complaint and worn rocker arms the expensive version of it. The unprotected radiator is vulnerable to stone damage, suspension bushes squeak as they age, and the recirculating-ball steering box goes vague and eventually needs rebuilding.

## Market notes

As of August 2026, classic.com's aggregate 107-series page records an average sale of $26,347 across 258 listed cars, with the lowest tracked result a 1979 450 SLC at $500 in September 2025. The per-model benchmarks show how far the range has separated. The 560 SL sits at a CLASSIC.COM Market Benchmark of $30,529 on a rising trend, average sale $30,363, with the deepest supply at 112 cars. The 350 SL benchmarks at $19,492. The two high-volume middle cars are the weak ones: the 450 SL at $14,801 and the 380 SL at $13,737, both falling. Scarce European variants sit above both, the 300 SL at $31,768 and the 500 SL at $28,459, each on single-figure supply. Spread within a model is wider than the gap between models: tracked 380 SL results run from $900 for a 1982 car in October 2023 to $40,464 for a 1985 in June 2026, and 450 SL results from $1,450 to $78,900. Auction evidence tracks the benchmark rather than exceeding it - RM Sotheby's sold a 1989 560 SL in Arctic White over Royal Blue, chassis WDBBA48D5KA100661, under 53,000 miles with a color-matched hardtop, for $30,800 including buyer's premium at Arizona in 2026.

## Value trajectory

For most of the 2000s the R107 was the cheap way into a classic Mercedes, and the volume cars have not fully escaped that. Hagerty's profile of the 560 SL recorded values falling in every price guide update from January 2017 to September 2018 for a net decline of 12.58 per cent, with 71 per cent of insurance quotes going to owners aged fifty-five or over. What has happened since is stratification rather than a general rise. As of August 2026 classic.com has the 560 SL trending up at a benchmark of $30,529, while the 450 SL and 380 SL - the two highest-volume variants, together more than half the roadsters built - are both trending down at $14,801 and $13,737. The scarce European cars have pulled clear, the 300 SL at $31,768 and the 500 SL at $28,459 on almost no supply. The SLSHOP's own market commentary describes low-mileage late cars commanding the highest premiums while renewed interest in early cars follows rising W113 Pagoda values, which is the clearest statement of where the money now sits: at the two ends of an eighteen-year run rather than in its middle.
