As a librarian, I haven't had the opportunity to buy a lot of bikes so I've maintained this '00 M750 for 20 years now. I have the chance to buy a new bike, but I'm torn on what to do with this one. My moto repair shop says it probably isn't worth so much anymore. Should I pickle it and put it on display in the garage? Have you ever been faced with a decision like this? What did you do? thx!
