Used Vehicles became more valuable over the past few years as new vehicle production was issued halted in early 2020 and supply chain issues plagued manufacturers for a few years after that. Used car prices are just now starting to come down. I hardly ever saw cars for sale by owner that didn't have over 200k miles on them and weren't models plagued with major issues. People were still asking $5k for absolute junk. My advice over the past few years has been to buy a new car as it's a much better value over any used car at the moment.
