We bought a new car last year.
Salesman didn't want cash. Repeatedly tried to sell us finance, leasing, PCP or whatever.
We were on the verge of walking away before he twigged that it was cash or nothing.
Suppose he lost some commission by not selling finance.
To be fair I get that they want to sell you credit, and thus get two lots of profit, but refusing to sell you anything, unless he is genuinely confident of selling a short-supply vehicle to someone else, is surely nuts. Does it really work as a sales tactic to piss off the customer ? Do they really grit their teeth and beg to buy a car?
Last car I bought was so easy. Stopped in garage on the way to an evening out - test drove the car I'd fancied but didn't like it, saw another which seemed very cheap, it drove like a dream so offered a token amount less than the ticket price and we shook hands on it. All done in half an hour including two test drives. I've just completed 100,000 miles in it (on top of the original 3 owners' 70,000). Not bad for a £2500 car. To be fair I did have a new engine put in a couple of years back, but it's still been luxury bangernomics for 10+ years
