| 2014 | $18,121 | +3.72% |
The table shows mixed year-over-year movement, with one recent year moving down and another moving up. That gives you a chance to shop selectively, since pricing is not moving in just one direction across the model years shown. The 2014 and 2015 model years have held their value best, with the smallest year-over-year price changes.
Should I buy a used Mercedes-Benz SLK now or wait for the next model?
Buy now if:
- Price trend: The 2015 model is at −6.21% versus a year ago.
- Deal availability: The 2015 model has 34.6% good and great deals.
- Sweet-spot year: The 2014 model has the most listings at a current average price of $18,121.
If you're buying used today, the 2014 model year offers the best mix of value and availability. If you want the newest version, it may be worth waiting for 2017 inventory to mature.

When I drive my car I feel like that I control the road and take on what is ahead. I feel safe because I know that my car will react and protect me. Weither its the multi air bags or just the way it handles the road with its quick stoping power and its handling. SLK is a class of Luxury and well known among MB owners. Enjoying the ride instead of just riding is a plus. I am sure when you purchase a MB you will be pleased.
