You can ask the seller to fax or email a copy of the title so you can have any Honda dealer run the VIN to check for any recalls, crashes, etc. If the seller is legit, he should have no problem doing this.

Since you are "several states" away from the seller, why not find another Forum member who lives near the seller who can go out and inspect the bike for you...as well as give you his impression of the situation. We used to do this on the GL1800riders forum all the time. Most Forum members are good guys who would be happy to help you out.

Have you seen lots of good pictures of this bike? It sounds like you may have somewhat of a queasy feeling about this seller...trust your gut...
