The Mercedes-Benz SLK-Class is a luxury roadster built by the German manufacturer Mercedes-Benz since 1997. The name was chosen to reflect the company's intentions for the car - that it be Sportlich (sporty), Leicht (light), and Kompakt (compact). There have been two generations of SLK cars from Mercedes-Benz.

The vehicle is perhaps famous for its retractable hardtop. While it did not pioneer it, the SLK revived its usage in modern automobiles. It was soon followed by the Peugeot 206 CC, Lexus SC 430 and the Mercedes-Benz SL-Class.

1998 - R170

The R170-platform the SLK 230 Kompressor was introduced in 1997 for model year 1998 to compete with the Porsche Boxster and BMW Z3. Setting it apart was its folding hardtop, but this added weight, denting the performance of the 185 hp 2.3 L supercharged I4 engine and automatic transmission. The SLK was on Car and Driver's Ten Best list for 1997.

A 5-speed manual transmission was added for 1999, but it was the introduction of a 215 hp 3.2 L V6 and 6-speed manual transmission in the 2001 SLK 320 that really brought the Sportlich to the car.

A AMG model was added in 2002, with a 354 hp supercharged version of the 3.2 L V6. This SLK 32 AMG was the best-performing SLK ever, and was a direct rival of the BMW M Roadster and Porsche Boxster S.

All Mercedes SLKs were built in Bremen, Germany. The very first Mercedes SLK was completed on January 29, 1997. The final 2004 Mercedes SLK was completed on April 7, 2004.
