Just ask Tumblr.

They do an after purchase check on the car, and the cars sold have a post-sale warranty.

Both CarMax and Carvana offer a one week refund policy, and a post sale warranty. The warranty doesn’t cover everything, but they won’t be selling a car they expect will immediately fall apart, cause they’d have to eat that problem.

I assume if they end up with a piece of crap, they’ll sell the car to an auction or scrapyard to recoup what they can.

Get an electric leaf blower for whatever brand of cordless tools you have and blow off all the dust before coming inside.
