-Yeah, if you pay someone to do it
-No
-Parts no, tires yes
-No, unless you drive supercars every day
-Yes, it takes premium but its not too bad on gas (20+ MPG mostly city driving)
- Thats more of an opinion than a fact, I'm not crazy about many of their other cars.
- Yes, it more or less has the drivetrain of a '98+ SLK.. Not really a good or bad thing, just a thing.
-Better in what sense?
The Z is more powerful but is a more cheaply produced car.
The WRX doesn't really compare (Sti is a different story).
I don't like M3's and I'd be more worried about maintainance on one of those.
the miata might handle better but doesn't really compare in terms of power, comfort or anything else that makes a car a good daily driver.
s2000's are better sports cars to drive on a track but are very small on the inside and doesn't make the same torque.
I haven't looked into Mr2's enough to compare, but I know I don't want one lol.
Rx8- no torque, burns oil.. not my kind of car either.

The crossfire makes a great daily.. I'd rather drive one than any of the other cars mentioned as a daily. If I were going racing with the car every week, I probably would have chose something else. It doesn't make scary power, but the engine makes good torque, so you can pass people without revving it out to 8k..
