Several years ago. I bought this vehicle from the daughter and son-in-law of the original owner. It was sitting in a barn on 4 flat tires. covered in pigeon crap and a layer of dust. At the time. I didn't even hear it run because the battery was dead. With the help of a buddy. we got it on a trailer and towed it home. Once home. I rinsed off years of dirt. to discover it needed a paint job. It has "patina" (lol) I put fresh gas in it. I replaced the spark plugs. wires. distributor. rotor. points. etc. I changed the oil. coolant/radiator hoses. and transmission fluid. Finally. I charged the battery. and inflated the tires. With much anticipation. I turned the key. and it started right up. It was loud as hell. and there was an exhaust manifold leak. Since this was beyond my skill set. I took it to a shop. where they replaced the left exhaust manifold. exhaust manifold gasket. head gasket and intake gasket. In addition. they adjusted the (4) wheel drum brakes. After driving it. as-is for several years. last fall I had a new dual exhaust system installed. This spring I put a new battery in it. and it fired right up after sitting all winter. The GOOD: Trim and Bumpers are in nice shape. The Factory GM Rims look nice. Factory AM/FM Radio works. Trunk looks solid. The glass is good. The interior looks nice. however there is a split in the drivers seat cushion. Power seats and front windows work. Original AM/FM Radio works. Cool speedometer still works. Tilt steering wheel. The BAD: Needs body work and paint job. has dent in left rear fender. and small crease in front right fender. A/C not working. never used it. Retractable headlights not working. the electric motor is unplugged. Power antenna not working. Rear 1/4 windows not working. Not sure if this is a "matching numbers" engine. It is a Buick 430 CI Wildcat. just not sure if it is original! To reiterate. it has a faint odor of "mice urine" which becomes more noticeable. when the windows are closed and the car has been in a hot garage. That's why the carpets should be removed and properly cleaned. or replaced. If Buy it now is used. or a reasonable offer is tendered. I'll include all the Factory GM manuals I have. as well as sales brochure. and laminated wiring diagram. and Riviera Owners Association Magazines. This is a nice car. it is almost 50 years old. but it is still nicer then some of the basket cases or parts cars that still want my asking price!
