Both bikes are on Craigslist, neither within 3 hours of me. The Montesa needs a fan motor and a "carb cleaning", the Sherco just says "runs good". I haven't made contact with either yet. https://albany.craigslist.org/mcy/d/00-montesa-trials-315r/6650430920.html https://rochester.craigslist.org/mcy/d/2002-sherco-29-trials/6680319796.html So, all things being equal, which would the collective go for. I'm a novice/beginner/rookie old guy and value reliability over performance.
