I think it is important to buy these cars from good responsible people. so judge the seller and how he took care of it.
A friend had a ppi done on a 996 turbo today and the mechanic said the tires are rubbing the inner fenders when turning and the car was stored in a barn and smells like manure...no way would I buy a car like that.

 

Thanks all, let me know if you know any good 951 for sale.
