Transferring warranty

Hi All

Looking at a 15 month old Chausson 640. The dealer says the warranty is not transferable, and it will come with a 3 month warranty. My understanding is it would have come with a 2 year base warranty and a 7 year water ingress warranty. I’ve emailed Chausson and waiting to hear back, but in the meantime anyone have any previous knowledge re Chausson ?

Thanks
