I am very sure thanks Phil.
I've had trouble with all my local London dealers, with multiple cars, including, Citygate Ruislip, Chiswick and Twickenham.
I brought my car from Martins and have always had top notch service. My Dad also brought his car there and has also had no problems.
In fact I drove out of my way to have my car serviced (cheaper than london) at Martins and again had no problems.
Sorry if you had a bad experience.
