Nice to find a good garage that is local and doesn't cost the earth! A friendly family business that I have got to know by having my car fixed, my fathers and now my 2 sisters. There are many out there that say this needs doing and that ...... My sister just taken her car there, I myself was thinking head gasket as a worst scenario as sludge was building up inside and was firing on 3 cylinders instead of 4 etc.
Great news for sister - ' new spark plugs and oil change, and take the car for a long run now then! '
Thanks Kevin, and crew. A garage you can trust!
