A used Mercedes Benz SLK's value largely depends on its year, mileage and condition upon appraisal. As an estimate, a used 2012 Mercedes Benz SLK with average mileage and in decent condition will usually be valued around $24 -25 thousand, but can cost around $30,000.
The Mercedes Benz SLK was introduced in 1996. It is a two-seat, hard top convertible. It has gone through three generations and the most recent is the R-172, which was introduced in 2011. SLK was created as a sporty, light, short car (sportlich, leicht, kurz in German) and an affordable alternative to the SL-class of Mercedes.
