The two tractors I have boughten were purchased off the lot. It made them easy to test drive. Rather than getting my G2160 from a nearby dealer because my dealer said it looked too weathered, he ordered me a new one. I would think that if the seat, paint, tires, hoses... don't look weathered, then you shouldn't have a problem.
Mine our sitting outside right now getting "washed" by Mother Nature /forums/images/graemlins/smile.gif. It's about time we got some serious rain around here, they were getting quite dusty and bird poop looking, but then, they are tractors....
