I suppose we all have our thoughts on this.
I've found RAC/AA inspections on cars like this are a waste of money. They come out with crap like the brakes are noisy on a car with cross drilled discs but miss a broken spring.
BMW are not much better.
I suppose all of these people will help you find a car that's not been crashed and trashed but a goog Indy is probably better at checking specialist cars out.
Never buy on someone else's recommendation.
A shitter to me is a scuff free car that looks repainted, I'd rather see the scuff nd know why I might want to paint.
Each to their own but a used car is just that.
