I supplied a £7000 1996 Mazda Bongo campervan to a lady who happily test drove it along with her nurse friend on the day of delivery. It was a tad slow to start, so I advised, and paid for a new set of glow plugs which she agreed her mechanic friend would install (We live 200 miles apart).

For whatever reason she towed the van the next day on a piece of rope, and without servo assistance crashed the vehicle. She did not tell me this, only that the vehicle would not start, on arrival to exchange it, i saw the crash damage and noticed the engine was burned out, and the radiator was broken indicating loss of water. She claims the engine was like this when she bought it and wants to reject it under the sale of goods act, paying me £700 damages for the crash damage which she obviously admitted to.

Would she have a case ?
