Would you purchase a '91 with 230,000 miles if the PPI was clean and all maintanence performed within last 5,000 miles/2 years (WP, belts, pads, spark plugs, clutch). Price $18,500.00. Everything checks out, but 230,000 miles. How many more miles can you put on the car and transmission? Great deal or just asking for trouble? Would be interested in Prime members advice. Thanks.
