Thank you DX100uk, Your advice is very much appreciated.
The new car was described as having a full VW service history. Before agreeing the deal with the dealer, I enquired whether the cambelt had been done as it is usually specified every 5 years or 80,000 miles (whichever sooner) and I recently did it on my car just to be on the safe side. When I asked the dealer he checked with someone else and told ne that VW had changed the schedule for this and they now state it does not need to be done until 130,000. I felt a bit stupid for spending the money to replace the one on my car but accepted what he said as he was the expert.
Regarding the overdue major service, I had no idea that it was overdue until I received the car and looked through the service book. His advert states very clearly that the car comes with full VW service history. The dealer has no removed the advert from auto-trader (before the car was delivered to me) and his own website (today) but I downloaded the brochure from his site before it was taken down so, I have a copy.
The problem with reversing the deal is that It is impossible as he drove away a working car from my property and it is now undrivable and can only be moved on a transporter. He has both V5 documents and did not leave me anything for me to send of to the DVLA as he aid that he needs to deal with this so that an extra keeper is not registered.
He said that he will call me tomorrow when he has checked over the car he took from me. I asked him to communicate by email but he said that he will call.
I've tried to notify the dvla of the change of keeper for my old vehicle but I need the V5 reference number and I dot have it. I have a similar issue with the new vehicle. I have the invoice from the dealer stating the registration numbers, the figures agreed and also I have proof of my payment.
I'm going to email him again now to say that I need all communication by mail as I have a disability that can make verbal communication challenging.
What should I do if he refuses to register my old car to himself, or the new car to me? Should I push to get the Services brought up to date an should I push for the full 12 months warranty that he agreed for the new car before he was dissatisfied with the old car?
Many thanks
