Gosh, a 58 Corvette has a plastic sort of body, and if it's fuel injected, it's worth a bundle. Collectible is all tied up in desirability and scarcity and fantasy. You can't make any good judgments about collectible in the first years, except in very rare cases. And, while I think 80's styling is really ugly, 40 year old people remember it fondly from their childhood and might actually want to own a mid 80's scooter. If I like the machine, then I like it. If you don't, but I do, well, that's sort of the baseline of owning a scooter anyway.
