My dad is buying a 85 300zx turbo with 99,000 miles. The digital climate control does not work and heat feels like it is coming from the defrost when I test drove it for him. Also the previous owner says that the A/C system was converted from R12 to R134 and the a/c does not work. He said it might need oil or something else. Asking price is 1500, is it worth buying for the mileage and maybe fix the problems or just buy clean up and re sell ? Also, did Nissan do the fuel injector recall on turbo 300zx motors ?
