Every 30 thousand dollar millionare aspires to (and can lease) a BMW 3 series, and keep in mind 90% of people don't even know what BMW's M line is anyways.
Are those really the people you want to be your peers? Cellphone kiosk workers and restaurant managers living above their means?
I recommend the Lotus Elise SC- the cheapest almost supercar money can buy that looks exotic as all hell. It's actually CHEAPER than the overweight M3. What does an M3 weigh these days- 3600 lbs? The Lotus is 2006 lbs. All newer BMW's are ugly, overweight and way overpriced.
The only problem is that it is made by a second world country, but hey, what can you do.
