I purchased a VW Touareg from an approved VW dealer last July. Since that time I have been in regular communication with them to obtain the Full Service History. They have not been able to provide this, most recently claiming VW had owned the car and therefore they are unable to supply this due to the Data Protection Act.
How much will this effect the resale value of my vehicle? And as I took out a further two year warranty, from the dealer, will this be valid as the policy is through a third party insurer. Please note the dealer has offered a free service in way of `compensation`?

Thank you
