I just got my SLK and LOVE it! Its exterior is so sharp, and the car is so fun to drive. (I'm one of those crazy "have to have a manual" for fun factor!) I look forward to warm weather and being able to drive with the top down. The car is quiet. I love having the navigation system and the stereo upgrade. I don't know about the reliability as the car is so new. Vroom!
The retractable hard top sold me. Holds road around corners so well. Shifts smoothly.
