Although all of them are great cars. The 911 is my dream car, and the new vette demands respect, the M3 is definately the best mix of all of them while probably holding more resale later than the rest also. I'm still not sold on the interior build quality of any GM as they all fall apart much quicker than most any foreign car brands. The Porsche although gorgeous and fast is not very practical for daily use. I'm sure i'll get jumped on by all the domestic lovers but let's remember this is just my opinion.
