Ok.......Carvana showed up on time. The guy was driving a Prius, so I wondered how he was gonna take both cars. They are doing so much business that they don't have enough company rollbacks to deal with it all, so they have contracted out 3rd party tow companies to pick up vehicles for them.
The guy had all the paperwork ready to go, he explained it all to me. They had all the places marked that I needed to sign.
His test drive consisted of starting my car, listening to it idle while we talked, then he pulled the car forward about 15 ft, and backed it up. That was it. He got my title and paid me electronically (which I requested vs getting a paper check). I got a confirmation text and email from Carvana telling me that my money had been sent.
The guy put a lockbox on my drivers side window, like they do at the car lot, and told me someone would come by and get the car today.
We exchanged niceties and he left.
Total time of sale and payment, no more than 10 minutes.
The tow truck came and got my car within an hour of him leaving.
So I would say that the experience with them was positive.
Round 2 with my truck tomorrow.
