I agree with John here. It is purely conjecture and speculation that is written her as we are not in full knowledge of the case or qualified solicitors. Therefore one should not wave the branding iron around.
IMO, buying a caravan from a dealership should give the purchaser both peace of mind that the van is genuine and also give the new purchaser reasonable financial protection should the van be found to be stolen prior to that point of sale.
I actually bought my caravan via a well known dealer in the forest of dean. At their Gloucester depot, they had a new fleetwood van that had been "lost at the factory". It was a 2006 model that had not been "found" until late 2008 and then registered as new. needless to say the peculiar explination did ring alarm bells. I then bought my van from the forest of dean depot. I negotiated a £1000 discount for cash sale and had the van serviced by them and a new 110amp batery fitted. Now, I assumed that the dealer would of registered the transfer of ownership with CRIS. However they didn't. I have susequently registered the change of ownership myself. But it is a worrying process as you are clearly told by CRIS that they will automatically inform the police if the van that you have bought turns out to be dodgy.
I think it's about time that CRIS and a form of proper registration of caravans with perhaps the DVLA is devised. At lest then you would have some sort protection that is readilyquantifiable by way of a PNC vehicle check. By the same token, I would expect caravan dealerships to be able to be brought to account, if they sell caravans that are part of the CRIS scheme.
To me it seems that given the current situation here, your no better off than the guy who buys his caravan through the local private sale adds in the news paper.
If I was in Natsdad's position I would certainly not pay out any claim of cash entitlement until I've been instructed to do so by a court judge. I would also consider sueing the dealership not only for the value of the caravan bought in good faith, but also for my legal fees and also for the emotional distress caused to me and my family.
