Do you plan to sell ASAP? Otherwise, it's kind of meaningless what Carmax is listing at. Dealers have been throwing crazy list prices on desirable used cars and seeing who might bite. The market is changing though. The supply chain issue is getting better and inflation and high interest rates are starting to impact both new and used car sales.
I've been in the market for a 2002-2004 Corvette Z06 for about 4 months now. The asking prices were beyond bonkers and the crazier the prices got, the more Z06s started popping up as these sellers figured suckers were paying those prices. Thing is, hardly any of them are selling and remain for sale for months on end, even at dealers. Just until about 3 weeks ago, have I seen the asking prices start to drop and some actually becoming somewhat reasonable. The point being, stupid high list prices for new and used cars is subsiding and will likely plummet over the next 6+ months. If a recession hits, a number of people will lose their jobs and many of those people bought cars at stupid high prices and will be desperate to unload as they can no longer afford the cars.
