Avoid Avoid
Avoid Avoid. Just been well and truly turned over by Martin Service dept. First ever visit. Took my 10 year old Skoda in to have an intermittent fault on the radio/Sat Nav system looked at. Mentioned to the service staff that the car was 10 years old so not spending a fortune on this problem. Got a quote four hours later for £511.20 for a new aerial but it might also need further work! Obviously declined. Went to collect the car and was told that there was a £199 charge. First time it was mentioned that there would be any charge at all. Why would I even think about spending £199 on a 10 yr old car for a quick report telling me about a fault I was already aware of? No doubt because of previous customers the guy on the desk had even highlighted the figure on the paper work with his yellow pen...pathetic.
Wish I looked at Truspilot before getting the full Martins treatment.
