looking for a 3 seater for my girlfriend and have come across these two skis somewhat local to me. the gtx has a rebuilt motor with aprox 30 hrs on it and looks to be in great shape. the xl800 has aprox 180hrs on it and looks to be in just as good shape. both are the same price, which would be a better funner more reliable ride for her? I understand the xl would have to be rebuilt sooner but how long do these motors go for?
