Hi velsatisfied - thanks for the advice, I was already pretty sold on getting one, but have done alot of searching today and it looks like the one i've been offered is suspisciously close to spydermans troubled car that i'll look for another - wouldnt have bothered me if he'd had all of the work doen under warranty, but his last post sounded like they couldnt fix the engine problems so sold it on - it is the same colour, spec, age and I checked history today to find it had the same change of owner date as quoted by spyderman when he bought it. Shame, will keep looking! Incredibe amount of car for the money, which is why i've been looking.
This forum has and I'm sure will continue to be invaluable, thanks to all!!!
