I found a Kitty Cat around the corner that I am interested in for my daughter. I really don't know much about them. I think it is a early 70s model. Seat has been replaced but other then that I think it is all original. The track looks kinda crappy, dry rot. It does run and it started right up. I don't mind doing some repairs, but I don't want to dump a ton into it. It has break away ski's the guy said. Sound familiar? They looked like they were not lined up well. He's asking $500 for it. I wouln't mind a better track for it so she can actually ride it in snow and not the driveway. Any advice or how much average replacment parts cost?
