Selling for owner, he has gone into assisted living. Vehicle has always been stored in garage. It has 21,000 original miles with recipts of work to show progression of milage over the years. Interior is about as good as your going to get besides being new. Exterior / body can not find but two flaws. two areas about the size of a pinky nail were paint has chipped. Tires are Michelin rain guards and have less then 500 miles on them. About a year ago he had car taken in and had new intake, new carb, all new ignition put in at the tune of $3,500. Wasn't needed but he states it was needed to run unleaded gas? Car drives better then my 2016 ford. Please look at pics and tell me what you think if interested.
