Eighteen years of definitive Mercedes grand tourer — from early 350 SL through V8 360 / 380 / 420 / 450 / 500 / 560 derivatives.
Launched in 1971 to replace the Pagoda, the R107 SL ran for eighteen years and over 237,000 units. The family includes the original 350 SL (3.5L V8), 450 SL (4.5L V8) — the dominant US-market car for most of the 1970s — and culminated in the 560 SL (5.6L V8) sold primarily in North America from 1986 to 1989. A 6-cylinder 280 SL and various 380/420/500 SL variants populated European markets through the run.
The R107 is one of the longest-lived single-platform Mercedes designs and the foundation of the modern collector SL story.
The longest-running Mercedes SL — accessible, well-supported and an established useable classic.

Start with identity, paperwork and originality. For the Mercedes-Benz R107 SL (350/450/560), the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Original paint, full Mercedes-Benz Classic documentation, both tops present, no panel corrosion.
M116/M117 V8s are robust; timing-chain rail and tensioner condition, head-gasket and injection-system service are key inspections. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
Final-year 560 SL (US) or late 500 SL (Europe) with low ownership history, original paint and Becker Mexico radios. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.
