Black, in good condition, new tires, clean, runs well, ac and heater fixed, new windshield, new wiper blade, staying on top of oil and filter change, good on gas, it's a classic car, I'm going to be moving and I can't take it with me, I'm asking for best offer, give me a price and we can negotiate.
