G3fizzle all the way..i've always wanted that car and soon will have it. the coupe would be my pick with the sport package that comes with the brembo brakes...yeaaa boi..
for your budget i'd actually go with an e36 M3 1999 those will out perform just about every car in your price range and they do have alot of style to them thats just my 2 cents though g35's are nice too but hands down the bmw ftw on power and handling abilities
