I'm not trying to be mean or something, but this car is NOT a M3....M3 looks different, and I feel sorry for seeing that M sticker on your steering wheel, and your claim about M's smaller steering wheel. I hope the dealer didnt sell you with the price of M and hope you have caught that.
But regardless, it is still a nice car even when it is NOT a M.. Its performance and look are still unbeatable..
Congratulation, and sorry to point out that its not a M.. By the way, I drive an IS250 if that makes you feel better.. :)
