Easy to change oil, most auto parts stores carry filter MB SLK320... $98.00 if you take it to Jiffy Lube... I wouldn't worry too much 7,000 miles between changes.

Tires depend on your style of driving.

I wouldn't worry too much about maintenance either, the car comes with a great warranty... But it's just a Mercedes SLK320...

No cruise control light ???? never saw a car with one... And yes AM sucks, but so do the stations on AM...
