No real trouble spots on this car. Since you're looking at one you already know its good points. The $ you have is appropriate; don't be afraid to spend money on a well-kept car - you'll pay for what you get. The only thing to look for, as with any used sports car, is any indication of abuse ie sloppy shifter, slipping clutch, excessive body-work problems etc.
Good luck. The main thing to remember is TAKE YOUR TIME; don't be in a hurry to buy the first one you find, unless it's the right one. Your patience will be well rewarded with a fabulous car.
