when you say Caravelle you mean Multivan?
here in Scehrmany the Multivan is the one with sliding seats, rails in the floor and lots of plastic/finishing. the Caravelle has fixed seats, basic panel co verings and maybe an extra A/C thing for the rear.
had a look at a few multivans and discounted them. not that much space in them. if you want to use the bench seat for sleeping you need the weird table thing in the rear which eats up space. putting the bench into bed mode requires lots of pushing and pulling and leaves you with very little room to do anything else.
had a look at a six seater LWB with closed rear panels. will go and have another look on thursday and will prob buy it.
as said above… enough space behind the 2nd row to lie down (and not have to stow the bed away), can seat six people.
also think many of the Multivans are overpriced for what they are and the mileage on them.
prefer to kit the motor out to my specifications.
