1985 Buick Riviera grey cloth Additional Info:

1985 Buick Riviera in very good condition overall. The Good: only 50k miles, runs tip top, cold air cond, paint is not cracked or faded, vinyl top is in like new condition, main headliner has been replaced but visors and side panels have some wrinkles and sunroof cover needs some TLC. 4 matched Michelin tires with about 75 percent tread, both bumpers are in good condition. Rides like you are on a cloud. No squeaks or rattles. Presently being driven some so mileage may go up a little. This car has never been on a salted road.
The not so good: dome lamp not working, power mirrors not working, power antenna not working (may just be from sitting in garage so much) The front bumper filler panels have been replaced but the rear bumper fillers are in bad shape (just fell apart from age-car has never been outside much) and the rear bumper guards are rusted.
The drivers seat has a small place on the edge bead that is frayed.
