Get it as cheap as you can but the forks will not last long- The rest will last ok And the frame is bombproof. If in perfect condition $110 is a good price but it is still a low end bike.
I had a 91 ?820 and this still comes back to me for service every year since I sold it.
No major parts replaced, only tyres, but it is rigid forks.

Even as a beater Bike- I would not want one again but they are bombproof.
