Proberly due to the conversions and rot. LHD's are often Westys that are more desirable. RHD's are sometimes rotten as there often UK busses. RHD vans are far more respected though
Obviously the pinnacle of value would be right hand drive (because we're in Great Britain) and imported from somewhere very hot and dry and hundreds of miles from the sea and it's salty corrosive atmosphere. Ummmm Australian then. Ho Ho! Lucky me and my Australian import.
LHD from europe are normally better comdition and people not as snobby about them these days like they used to be but people will pay the premium for RHD. Look on autoscout24.de
i don't think much difference in price but 2 vans in the same condition and the rhd will be more desirable and easyer to sell
If you have a lhd and a rhd in the same condition, the rhd will probably attract a premium in this country.
LHD tend to have had less rot and therefore less mending/bodges done to them. I bought my leftie for this reason as it was untouched underneath and solid. All of the RHD I'd seen had been mended in some way.
