2009 swift ace siena very bad damp in all of rear

Hi.
We bought an 2009 Swift ace siena  from a dealer on the 04/03/2016 it had 12 months MOT and
a habitation check certificate showing no faults or problems and only 13000 miles on the clock, the seller told us that everything was ok.
One year later on our return from Spain we took it for another habitation check to be told the rear end
floor was rotten and delaminated, Needing £4500 to repair it.
My question is....  Is it possible to sustain such damage in that time in a hot country with little or no rain
parked up on a camp site???
Is it possible the habitation check missed it or was it noted and ignored ???

I would say, contact your local Trading Standards, and get their advice on the correct way forward. Sadly, some dealers have a reputation for being very slippery customers, especially when your money is safely tucked up in their bank account. Good luck with any action you take.

Thanks Debbie.
I have taken your advise and started proceedings will let you know
how I get on.
 Best regards.

Any news??
Good luck on getting it sorted!

Wouldn't a 2009 Swift come under their 10year habitation body warranty?
