Research the retailer's inspection process on used items. Make sure their methods adhere to current industry standards. You also want to make sure the retailer follows the strictest environmental regulations in their day-to-day operations.
It can help to involve someone who knows how to confirm the condition of the rubber tracks when buying them used. Take the individual to the store with you when you are ready to make a purchase.
