my friend had a audi a6 his transmisson f**ked up on him with like 3 thousand miles on the car.
3 series is a girl car.
C class i dunno which one you wanna get the 500? or the 350?
i would go with the c class
you should also consider a new cadillac cts got good lease options right now and its a nice car
How's he gonna take you seriously when you don't even know the models? There is no C500 C-class.
In all seriousness, what are you looking to get in the car? I had the old W203 C-class, and while it was VERY slow, it handled very well for stock (had the sport). My brother had the E46 and it handled a little better, the car was just more solid than the B6 A4 and the W203.
If you will eventually modify the cars, Audi wins just for the fact that they have turbo's and decent aftermarket community.
The BMW will be the best bet if you're just looking to keep the car stock, or eventually modify it. I will buy an E46 one of these days just to have because I have soo much love for that car. I know more about E46's than I do the cars I roll in right now lol. There are a lot of parts for BMW's, but for the most part (besides the new turbo's) the money you actually spent on mods, compared to the actual hp you get isn't really worth it.
The Benz is a good cruiser. I had the last production year W203 w/ the 2.5L V6. And while it was slow, they actually really made a difference with the "facelifted" W203. They gave them the AMG bumpers and some interior treatments, the car was lowered a tiny bit more than a reg W203, had AMG sways, Brembo calipers/rotors in the front, etc.
There's not a lot of modification for benzes, they seem to be mostly cosmetic, and if you do want performance mods, you'd have to get an AMG to be anywhere near the aftermarket support/community of the other two brands.
to sum it up, it all depends on if you're buying new or old. If new, I'd go with the BMW regardless. Liek others have said, the free maintenance is really worth it, and it's aroudn 2k to extend it to 6yrs/100k miles.
