I have a few original owner/rider manuals for older bikes and cars so I'm checking their value on eBay last few weeks. I'm not being greedy but the eBay one is going for $89.95 (free shipping)....
Update: I added a Suzuki TC100 manual note on the bottom. Same thing
This is the only other one I've seen, I have the exact same manual, in fair condition with a fold on the top front cover and a little discoloration (my picture below - and eBay link/picture following).
So what would be a "fair" price - no WAY I would pay 90 bucks for this.

Found the same seller with a TC100 manual - again $99.95 and $6.95 shipping !!!
There is one other for $34.99 plus $6.95 shipping
