Is there a way to find out my vans original seat set up. It currently has a passenger bench but only 4 bolts holding it down - my hunch is that the van originally had a single passenger seat? The registration doc now says it is a 6 seater so presumably if it was changed from a 5 seat kombi to a 6 by adding a bench seat the owner informed the DVLA to make it legit. Any insights as always greatly appreciated.
