Recently purchased from a garage a Q7 advertised as having full service history. It transpires that the car has a partial service history. This was raised with the garage and they have offered to carry out the missing service items. I have explained that doing service items retrospectively does not resolve the issue whereby the value of the car with a partial service history will be worth less than one with a full service history.
My question is where can reliable data source be found on pricing information for a car with partial service history and one with full service history. I intend on claiming the difference against the garage for mis-selling the vehicle to their financial benefit.
