My caution would be that you will not be able to return it to TSC for repair and parts support might be lacking. I think I'd look at go-carts sold at ATV dealers or somewhere they had their own shop and parts. If the price is comparable, my choice would be to buy there instead of TSC. If you save $500 and cannot get parts when it breaks, it's no bargain. Go-karts spend their whole lives being abused. That's just what they do. They will break sooner or later.
