Well I appreciate everyone's opinion concerning the tires. I didn't mean for it to seem like the money for the tires was a huge deal for me, I was just curious if I could put regular tires on it and save a few bucks. But the way some of the replies have said other repairs are very expensive it makes me wonder...are Crossfires known for breaking down and needing a lot of expenisve repairs? I know the car is made by Mercedes and of course a repair on something will be more expensive, but if the cars are built well and don't need repair often, it's worth it to spend a little extra money for the quality car.
