Warranty.

I have just bought a Bailey GT65 Verona 2013. The Dealer I bought it from said it was a van they sold from new and looked after. It has a full service history and when it was brought in for a service a couple of months age the couple decided to exchange it for a new van.

After paying for the van that now sits on my drive I have gone through the service documents only to find them empty with not even a record of the first hand over. I thought at first we had been given the wrong folder for the van.

I contacted the dealer and they say the owner has now said it has been serviced by a friend cash in hand for the servicing done. This not what the dealer said  me when I viewed the van. I'm really confused and don't  know what my right are about the wrong information given to me when I bought the Van. I now realize this invalidates any manufacture warranty on the van. As the reading for water ingress on some point were 15% they say this is fine as anything over 15% need to be checked and sorted. As 15% is on the boarder line I'm a little worried.

I only picked the van up less than 48 hour ago.

Any advice would be greatly received.
