Why is the little guy so afraid of sharing the final negotiated price on a purchase deal? Why the secrecy? It’s a publicly broadcast TV show! People are interested in the purchase cost, not just the resale price after he spit-shines and sells what he buys. He seems to have no problem speaking when he sells something at an auction for an exorbitant price.
One other observation: after any maintenance/engineering is done, carini (?) always does the test drive himself. As anyone in the auto repair business knows, the mechanic who performed the work always does the test drive. The mechanic knows the work he performed, and knows what to watch/listen for.
