Sold one to CARVANA!

I wasn’t asked to upload any pictures of my car. I didn’t do any video appraisal. I drove to the Carvana lot in Philadelphia. The gate was stuck was the Carvana employee came out and pushed it open and I drove onto the lot. The Carvana employee said " well, you obviously drove it here so it runs. Let’s go inside and finalize your sale" I went inside and signed paperwork and my payment was authorized. I owed my car outright so Carvana was sending me the ACH payment. After I signed my paperwork the Carvana employee went outside and took pictures of my car and took my license plate off and then ordered me a free Uber to go home.
