I unfortunately had a bad experience with Chapmans....
I found their service to be relatively friendly but the lack of attention to detail almost cost me an engine, no exaggeration. I fixed what was missed myself in literally 20 seconds.
Also some spare parts I had in the car were either kept or thrown out which was a bit annoying.
Out of all the places I have been too so far I only go back to Elite Racing, his attention to detail is incredible, he spotted problems that Chapmans and Mercury missed and that was before I even popped the bonnet.
I have witnessed Dan drive out free of charge to help his customers when they have encountered a breakdown (not releated to any work he performed). What other mechanics do that for you?
Nicest guy too....
Having said all this, I will have to give the newest sponsor Hardcore a go sometime soon, from all accounts they are a good outfit with the new management.
