Very Sorry and Surprised to have to write this review. As have bought many company cars from this dealer over the last 10 years. My wife has a 2006 CLK with a transmission fault. I already diagnosed the fault at home with ODB2 scanner and repairs already undertaken, so expected the standard we have to charge you £100 for diagnostics. However when Technician took the vehicle I was watching through the Service window and the work that was indicated should of been done was not. No scan was performed on the vehicle and no Transmission Fluid Level Check as I indicated which could also be the fault. Service Manage came out and I asked him had this been done and he said it had. Then looked through service window again and Technician attempted to look like he was then checking the fluid level but without taking the Transmission Fluid Cap off. Very disappointed with Mercedes Swindon after so many happy years of service from you. You have now lost another Fleet Customer.. Just because something is older does this mean you cannot expect same standards of service. John Highcock
