Whats the service history like ? The fact that the engines racing a bit could mean a few things, but as long as it dosen't knock bang and crash it should be fine. If you have got a little bit of money floating about get it AA inspected, It's about £200 I think ? Sounds about right for the money though, it's quite "desirable" too, even though it's a 1.1 106. If the service histories good then go for it I wouldn't bother even looking at the bumps and scrapes, it sounds condescending but you'll put loads more on. The Interiors where it matters, you don't sit outside the car
