@vwdasher Flxibles are the most collectible, I think, amongst conversion bus fanatics. Some friends bought a very rough 60s Flxible and traveled in it for a year or two.My favorite bus, and the one I think I'd buy if I were wanting to do a conversion, is the GM PD-4103.Flxible has the benefit (or negative, depending on your perspective) of being relatively rare, so collectors value them pretty highly. And, there are certainly some gorgeous ones.
