Our little green car, nearly 14, had quite a few problems, although still driveable. The best option was donation to the Kidney Federation. It has been through about 7 (!!!) collisions of one kind or another, and almost 200 thousand miles, but will make the next owner happy and safe too.
We go from a two car family ( I never leave the house, so what do I need a car for?) to a single car family, in a place with superior bus service everywhere. CHEAPER!
