Hi, I own a Mitsubishi car and whilst I am the current owner of this vehicle, we are suspicious about a service stamp in our service book which says its done by Mercedes Benz. Now, at the time fo the purchase the previous owner said he knew nothing about it but because it had full dealer service history except 1, it wasn't much of a problem as the car was fine. Problem now is selling it because when we contacted the Mercedes Benz dealer whose address is showing on the service stamp, they claim they never stamped it nor do they have a record of it. Heres a picture of it (click to zoom in) It clearly shows the offical Merc stamp, date and signature. We don't have a invocie for this service as it was never given. What do you guys think?
