All I know is I had a relatively clean, lowish mile (60k) 02 Camaro SS I listed on facebook marketplace a couple of weeks ago, and it sold in 5 hours. Then I listed a set of Weld wheels I took off the car the buyer didn't want (or didn't want to pay for anyway), and they sold almost as fast. Things are definitely slowing down, but I wouldn't say the market is dead by any means.
Yea, the sky definitely isn't falling, and things are still pretty hot for sure (especially compared to pre-2020). Just saying that, for the first time in several years, prices are noticeably declining on used cars and discretionary 'toys'.
Because I'm a nerd, I just took a look at the 'official' used car data from the Fed. Prices are ~20% off their early-2022 peak, but still ~20% higher than early 2020. The overall trend is still decreasing, though not quite as much as it was 6-12 months ago.
I deleted the listing earlier today, I'll wait till after the elections and then post it back up
Personal opinion, but I think it's pretty unlikely that the result of the election will swing the used vehicle market one way or another. And politics aside, used vehicle prices are probably going to continue declining, at least somewhat, due to broader economic forces.
On diesel truck prices specifically, there's two giant headwinds facing them: EPA's crackdown on aftermarket tuning, and the dramatic improvement in gas engine technology / performance. I love my LB7, but if anything ever happens to it, there's 0 chance I'd buy another diesel when there's as many good gas options as there is today.
Lots of other people are starting to feel the same way, which is going to push prices down.
