Dealer sold a car “ as is “ they put on lift for oil
Dealer sold a car “ as is “ they put on lift for oil changed and the frame was rooted through, how bad did they need a use car sale to sell vehicle under $10,000 that was clearly a safety risk ? Called to discuss switch managers and played good guy bad guy sales manager, if everything go’s well buying from that great, but any issues good luck dealing with unethical business
