I really love this car. I also own a 2004 SLK 230. All the issues I hated about the SLK 230 have been fixed with this new generation. Car does not hunt the road on rutted highways anymore, smoother ride. This car will get 27 mpg if you behave yourself. I can't say more about how much I love this one. This is my fourth MB and so far it is the best one.
Cornering, acceleration, smooth ride compared to my 2004 SLK.
Didn't buy the Harmon Kardin system. Stock radio stinks. MB should develop an an after market upgrade for those who did not buy HK sytem. Stock system really stinks. You can't really hear it very well with top down. A $50,000 car should have a premium radio without being gouged another $3000.00
