Found an '83 Honda ATC 185 (not a 185s) for sale on craigslist. Asking price is $550. Looks pretty decent in the picture. Ad says: "Runs great, complete, everything works, new brake cables, starts first pull, ready to go." This sounds like a really good deal! Any opinions? Are these collectible? I just joined the forum and I'm kind of a newbie when it comes to 3 wheelers. Thanks.
