I know a bloke who bought a new Ford F150 diesel V8 converted to RHD locally in SA a couple of years ago and cost him $154,000 he told me. He had a lot of electrical and engine management issues with it that no one could fix with a couple of other dramas that gave him grief. I don't know if the issues were conversion related but essentially, he bought a vehicle other than RHD conversion knowledge, the importers providing the warranty knew nothing about them mechanically and electrically and of course Ford dealers wouldn't touch it.
