No question it is expensive putting together a paddock set-up. But people leave the sport all the time and sell off their entire kit cheap. These are generally expert racers that have finally decided to walk away and do something more useful with their time and money. You can find some great deals that way. My #1 son and his friends ended up with a camper trailer they stored at Loudon for the years they were road racing. $700...They eventually gave it away when they were done.
They went from a F150 to an F150 plus a small box trailer to a F350 deisel pulling a 28 foot box trailer. Then they started going the other way, eventually using a Ford extended cab van. Now they race KTM's in the desert out west. A lot of equipment was bought and sold over those years. Seems it is always easier to buy than sell it. There lies your opportunity.
