I, too, am 76. Could no longer do 2 wheels and bought a new F3L. I still miss the easy handling and sensation of the two wheels, but with the Spyder at least I can continue riding, hopefully for many more years. Not worried about ever selling. May even get a new one in a few years. I would buy new if your budget can handle it. Can't think of anything else to spend the money on that would be more important!
