Buyer’s notes
About the Mercedes-Benz SL 300 (R107)
The R107 was offered with six-cylinder engines as well as V8s: the 2.8-litre 280 SL from 1974, added in response to the fuel crisis, and the 3.0-litre 300 SL that replaced it in the 1985 facelift and was built until 1989. The late cars are widely regarded as the best R107s, and the 300 SL is the smooth, economical choice among them.
What moves the price
- Era: the facelifted cars of 1985 to 1989 lead the R107 market.
- Body condition, the largest single factor.
- Mileage and a full service history, which earn real premiums on the late cars.
Before you buy, check
- On the 300 SL, the cylinder-head gasket and coolant history: a documented gasket replacement is the one to buy.
- Rust in the front wings, sills, jacking points, boot floor, windscreen surround and door bottoms.
- The hood mechanism and seals.
