i once had a look over a 1.4 ghia mk4 escort for a mate, cos he didnt know much about cars.

it seemed OK, only £400 so couldnt go wrong.

i remember saying to him "its a sound enough car, if the engine blows up next week dont blaim me"

a week later it had somehow got a dint/split in the sump (he says he didnt bottom it out, but some fucker did), lost the oil, the oil sender wasnt working, engine seized!
