Next came the SL-Class 230SL, a new design with a low waistline and big curved greenhouse windows, and a Coupe Roadster whose distinctive roofline earned the nickname "pagoda top." Around 1968 the engine received a displacement increase and the model became known as the 250SL. The last two years of production as the 280SL saw minor changes to switch knobs, and wheel trim rings became full hubcaps.

The 1989 Mercedes SL base model was the 228 hp (170 kW) 3.0 L inline 6 300SL version. But it was the 322 hp (240 kW) 500SL (with a 5.0 L V8 engine) which made the most headlines. The specification was high, with electric windows, mirrors, seats and roof.

1994 saw a mild facelift for the SL, and the 300SL was replaced in Europe by the SL280 and SL320 (with 2.8 L and 3.2 L I6 engines). The SL500 continued with the same powerful engine. A 389 hp (290 kW) 6.0 L V12 SL600 topped the range in 1993.

The SL320 replaced the 300SL in the United States in 1995, but the SL280 was not offered. The 6-cylinder SLs were dropped from the US lineup in 1998, leaving just the V8 and V12. The SL500 got a new 302 hp (225 kW) 5.0 L V8 for 1999.

1999 Mercedes-Benz SL73 AMG

The extremely rare SL73 AMG was sold through AMG in 1995, and at 525 bhp it offered the most powerful V12 engine ever put into an SL up to that time. After a brief gap, the SL73 was offered again from 1998 to 2001, although the engine was slightly updated to be more reliable. The same 7.3 L V12 was later used by Pagani in the Zonda. A total of 85 SL73 AMG roadsters were built. The SL73 was briefly reintroduced in September 1999 following the SL's end of life facelift and a limited number were produced up until December 2001. The facelifted SL73 is the car that appears in the picture (left).

The SL60 AMG was also extremely rare. Sold through MB from 1996 to 1998, it used a 6.0 litre V8 engine producing between 381 bhp and 384 bhp. AMG claimed a 0-62 mph (100 km/h) speed of 5.8 seconds. Its top speed was limited to 155 mph (249 km/h), but with the limiter removed, it was capable of approximately 185 mph (298 km/h). AMG later unofficially admitted that 0-60 mph was closer to 5.0 seconds and the engine produced between 405-410 bhp.

The SL55 AMG was sold through AMG in the R129 bodystyle from 1998 to 2001 in limited quantity. It was the predecessor of the production R230 SL55 AMG sold today.

Only about 300 cars in the SL-class were customized by AMG prior to 2003.

As the new millennium approached, the SL was a decade old and customers were turning to more modern cars like the Jaguar XK8.

In 2001, an all-new SL (initially just a 5.0 L SL500 version) went on sale, boasting the "Vario-Roof", an electric folding steel roof which had been seen on the smaller, cheaper SLK in 1997. A 5.0 L 302 hp (225 kW) V8 was optional, with a 5.5 L AMG V8 appearing in 2004's SL55 AMG. V12 engines are available in the SL600 and the limited-production SL65 AMG.
