I drove 3 hours to this guy's house to buy what was described to me as a mint 300ex (he even sent me "current" pictures where the quad looked brand new). I was assured that it was in tip top shape. When I got there I found a total piece of junk, rims bent, plastic destroyed, rust, clutch worn out, etc. Two of the engine case bolts were not even threaded in the case - they were just stuck in the holes (and they were too short for the case anyway). There was also a huge oil leak.
This joker lives near Akron, Ohio. Avoid him at ALL COSTS
