“Great friendly staff, really knowledgeable and helpful at fault finding, car kept losing coolant, leak discovered from water pump also offered to change timing belt whilst having same access, 1st time resolution. Happy with overall service.”

“The gentlemen at this garage are wonderfully polite, friendly, professional and extremely helpful! We had an issue with an alternator and needed to get to London the next day.
