I just bought a new car last week.

3 year old used models were going for what new ones were, so there was no point other than availability. Older than that, prices are stupid. As you can maybe tell by my username, I'm a Toyota fanboy - usually try to find something about 5 years old used. Those type of cars are still stupid inflated. Case in point : my wife's 2010 Camry got totaled, Blue Book Value had it worth 3500-6500, and insurance paid out nearly $9k (other person's insurance who was at fault). I paid $10k for it 7 years ago. Insane. And I don't trust Blue Book anymore.

Also Hybrids/electrics basically can't be gotten (at least from Toyota). Tried multiple dealerships. They're still dealing with supply issues. We put down a deposit on a non-hybrid model a week before it was built, still took 3 weeks for us to drive it off the lot.
