IF they ever even begin to attain "collector status", the ONLY ones that will do so are the near-mint, very close to stock, non-offroaded, non-rust belt, unmodded ones. All the others (which will soon be MOST of 'em!) will just be "another Japanese used vehicle", and valued accordingly...
My vote would be Rickshaws then and the Pearl Beauty in Colorado if it is still there.
