what to look for when buying a RX-7??
 

I found a 86 RX-7, non turbo, 5 speed, I'm not sure of the mileage on the car but it has a new factory engine in it put in by Mazda, that has 50k on it. I also has a new clutch. The lady wants 3k for it, is that a good price? What should I look for as bad signs when I go look at it and drive it? What can I look for as signs of abuse? How should I run? Does the engine have some kind of warrenty? I have been wanting one of these cars for a while now, this will be my first one.:D
