My sister's old original mini was a total rust bucket, new wings, inner/outer sills, floor pan, full respray and it blew an engine, brakes failed, but she loved it, she must of done, cos she spent fortune keeping it on the road.
Wisely, she saw the light and replaced it with a new Ford Fiesta Mk3, which has been totally reliable for 26 years and it just passed another MOT recently, what a star!
