If you want a high-revving sports car, which has modification capabilities and RWD, you should probably be looking for an RX-7, highly doubt that you'll find a good one for 3000, but its worth looking at. Some other cars id look at considering the budget are Nissan 240SX, or 300ZX, Mitsu 3000GT. However I would personally look for either a Civic Si or an Integra.
