When do you get your license..? If you have allot/decent of time before you get it, then i suggest possibly an old 65-71 v8. Find one thats in need of restoration, for say anywhere between 3-5K, then restore it yourself with someone who has some knowledge about cars. When your done, you'll have a kick butt car thats a classic, that girls will stare at, and a car that you truly will care for and respect because YOU did the work to fix it. Another good choice would be sn95's with a 5.0. Newish body style, and old school 5.0. (was it 94/95?)
Regardless of what car you drive, its key to respect is power. A muscle car is worthless if you cant handle it or wreck it.
