Definitely the most widely copied car on the road today in terms of style and design. Don't believe me? Just look at any Audi. BMW did it first.
Unrealistic: BMW M3, Mazda RX-8 (or an RX7), or a Nissan Skyline.
The Mazdas are unrealistic not because of their price but because of what I'd pay in insurance premiums for the privilege of driving them
Edit: is there some reason I can't post an imageshack hosted pic? I uploaded them there so I wouldn't have to hotlink, and now it's saying I can't use that extension...
