Get a prelude! I wanted to get a GSR, then I realized GSR has no torque (the thing that actually makes the car go fast off the line). Prelude has 156 lbs/ft of torque, and GSR has about 123 I think. That's not much better than a Civic! I got myself a 4th gen (96) Prelude and very happy with the quick acceleration.
Ask the general questions that you would when buying a used car. I had a hard time finding a Vtec prelude, and ended up getting a SI. I think all 5th gens have Vtec, and that's a good thing. Test drive the car, and always bring it to a mechanic to check it up before buying it. This is the most important!
Good luck!
