Probably the best of its type overall in Exmouth. Worth haggling as is always the case with these places, but they do try, and the service I have received has always been good. Do batteries as well as tyres, too, and the last one they sold me is still going at the moment.... If yours is iffy, its is worth having it tested before buying another, or getting stuck.
