I had a wild experience on Carvana. Bought the car (used, with 14k miles), they were going to ship it to my local Carvana pickup and the day before I get a message to effect of, "Hey we just tried to start your car and it's not starting so we don't recommend you buy this car" . All fees refunded, I was confused but grateful, no one followed up to try and get me to buy another car (other than garden variety email list marketing). Ended up buying a friend of a friends old car for way less two weeks later.
