the absolute best thing you could do, is have a good mechanic do a pre-purchase inspection on ANY used car.
post your city and maybe someone could suggest a shop for you.
The car should have tires that are the same model and wear, if not, that's a red flag.
At least, definitely drive the car on flat, dry pavement (not gravel) and see if it will do tight donuts , at idle or slight gas pedal pressure, without jerking or bucking. Just smooth tight turns. Try some figure eights too. You don't want to pay good money for a car with 'torque bind' problems.
