re: Is a car purchased from a used car lot lower when paid for by cash rather than financed?

Knew a guy that when he was ready to buy a car (new or used) he’d find what he was looking for then go to 3-4 places

He’d tell them to give him their lowest possible price.

Afterwards he’d pay cash and buy from the lowest priced place.

He said a few times other places would call him back and ask why he didn’t let them beat the lowest price he got quoted. He’d tell them I asked for your lowest up front if you could do better than you didn’t give it to me to start with.
