I bought this Trailer + Two Go Karts for the family. We have not had them out in two years. The red card was working great when we trailered it and I have not had it out since then. The Blue cart has a mechanical issue and will need some work. I am asking $6,000 OBO. They are both registered. The blue one qualifies as street legal if you can get it running again (blinkers, mirrors, etc.)
