C7 vs M3: M3 I guess because it's more practical.
CTSV vs Ghibli: I guess the Ghibli, at least that looks half decent.
Escort or AE86: Well the AE86 Corolla of course. Dat magnificent 4AGE engine.
Veyron vs Civic: The Civic, even if I could afford the Veyron I wouldn't want it.
M3 Evolution vs 190 Cosworth: This one is really ****ing difficult. I guess the 190 by a small margin though...
Euro city cars: Citroen because sure
Supra vs Skyline: Supra of course. And I'd leave it stock and one day probably make a fortune off of it.
914 or 924: Kind of a tough one, but I guess the 924. I don't really get the hate for it, I like them.
Diesel trucks: Ehhhhhhhhh Dodge I guess....
V8 Vantage vs 360: The Aston all day. Looks better, plus I'd rather listen to that lovely Aston V8.
Bentley 4.5 vs Mercedes 710: The Bentley, because I dunno it just looks cooler.
Ugly ass Corvette vs pink S2000: S2000, I ain't even that mad that it's pink. Either way I get an S2000 so that's a win to me.
Kei Sports: The Autozam AZ1, those are just so damn cool!
KTM XBOW R vs LCC Rocket: I guess the XBOX even though the Audi engine is probably a hunk of garbage.
Large luxury sedans: The Lexus because at least that one will be reliable.
Group C cars: The Toyota 88CV, because one of my favorite Toyota race cars. I want them all though.
GT legends: RX7 because why not
German sport wagons and sedans: New M3 because I absolutely love it.
Peugeot 406 vs Fiat Coupe: Fiat I guess? I dunno it looks less dull so why not.
Camaro drag car vs GT40: GT40 no question.
Early '00s sports cars: The Esprit in a heartbeat. One of my personal favorite cars from that era, they're just so damn beautiful.

and they sound phenomenal.
