Used car prices peaked around new years. People would throw stupid prices out to see what stuck.
Prices have been falling since then. Apparently about 15% at wholesale since first of the year - and that has a bit of a lag so I would expect actual dealer sell prices to continue dropping pretty fast in the next few months. Interest rates really just went way up in the last few months, so that will pile on.
First of the year there were No cars on the lots, now there full of used cars just when the OEM's are actually starting to deliver new cars as well.
Still its a supply side issue, so I wouldn't expect miracles, but its getting better.
