This was my dream car when it came out. I immediately traded in my BMW Z4 for this SLK350 "donkey". It was the worst decision of my life. The car does draw attention, if that is what you are into. The car spent more time in the shop than on the road. Replaced a manual transmission at 34K and now needs another. The engine acts as if it does not get enough air and strains in the lower power curve. The car is a reliability nightmare and does not perform like it has 268 hp, closer to 200 hp. Mercedes has consistently failed to stand behind the car and has denied there are issues even when they have released multiple internal documents on its poor performance. Last MB I will ever own.
Looks that's it.
Replace the engine and transmission. Redesign the interior to add more leg room for men rather than for women. Go back to the drawing board completely for the engineering. This car is pathetic.
