Going back a few years, but a bloke who was a mate of my Dad's showed a remarkable level of tight.
He won on a scratchcard, brand new Astra coupe (so around 2000 or so this would have been) and he was peacocking away about how well he'd done, but he wasn't keeping it as he needed the land rover ting he had as it was easier for his wife to get in and out of (she had arthritis).
He picks it up at the dealer and straight away asks what can he get for it, dealer naturally says about 5k below list price, second hand. He would still have been coming out with about £14k iirc.
the big man is so incensed that he isn't getting list price, he storms off and says he'll drive it for a year - so for the next year he made his missus and her walking frame get in and out of this motor, rather than just accept he's still 14k up
