Some people who have converted their cars to RHD have had their car totaled by the insurance company and given a salvage title. We live in America and we drive LHD cars, if you want a RHD Car, move to somewhere where you can buy them off the showroom floor.
It would only triple the re-sale value if you find the right sucker to by it, I would not pay any more for a RHD version of a any LHD version car I could buy.
