How unlucky mate - I think the only way to look at this searching for a positive is that you at least didn't get robbed for the £2k you paid and at least left with a car (albeit needing more work than you had intended)

Look forward to seeing this turn around.

I once bought a 172 Cup - which was soon named the crab (didn't drive straight) by my friends as it was clearly involved in a big accident and repaired with out being declared, any way thats another long story.
