There are tons of us out there trying to sell used karts, but it would be more helpful if we had an idea where you are located and where you might want to race. For instance, I’m in WI. I have a kart for sale, but if you’re in CA, then it doesn’t make a lot of sense for you to be interested in my kart, when they’re probably dozens in your area available.
