The Mercedes-Benz R129 automobiles were produced from 1989 through 2001. They were sold under the SL-Class model names. The R129 replaced the R107 SL-Class in 1989 and was in its turn replaced by the R230 in 2001. In the US from 1990 until 2002.
The R129 was based on the shortened floorpan of the Mercedes-Benz W124[4] and featured many innovative details for the time, for instance electronically controlled damping (optional) and a hidden, automatically expanding roll-over bar. The R107's rather dated rear diagonal swing axle gave way to a modern multi-link axle. The number of standard features was high, with electric action for the windows, mirrors, seats and hood.
Initially, there were three different engines available, the 300 SL with 3L 12-valve straight 6 (190 PS (187 hp/140 kW) at 5700 rpm), the 300 SL-24 with a 24-valve version of said engine (231 PS (228 hp/170 kW) at 6300 rpm) and the 500 SL with 5L-V8 engine (326 PS (322 hp/240 kW) at 5500 rpm), joined in July, 1992 by the 12-cylinder 600 SL ((394 PS (389 hp/290 kW) @ 5200 rpm). While for the six-cylinder cars there was a choice of 5-speed manual or 4-speed automatic, the V8 and V12 could only be ordered with the latter gearbox.

Princess Diana
In 1991, when Princess Diana sold her Jaguar XJS and leased a J-reg metallic-red 500SL, as she became the first member of the royal family to use a foreign car, this sparked a media storm as it questioned whether a member of a British royality should drive foreign cars. Media pressure forced her to return the car to Mercedes-Benz in 1992, which it now resides in the Mercedes-Benz Museum.
