I did the exact same thing and got my 2021 Model 3 this past Saturday. Hoping your delivery goes/went better than mine did. My car was not cleaned well and they used an automatic car wash which scratched the paint and the interior was dirty with dog hair, dirt, and grass in the trunk. Fortunately I have a really good detailed and reluctantly Vroom is reimbursing me for the detail. There were also a few blemishes that were not on the listing that I need to get an estimate from Tesla on correcting, once I can make an appointment with the service center.
What you’ll need to do is call Tesla customer service and tell them you bought a pre owned Tesla from a 3rd party. They will have you email in your purchase agreement, title application, email address, VIN, Home address, and tell them you bought it from Vroom. The email address is
[email protected]. I was told this would take 3-5 business days to happen, and today is day 3 and nothing yet. Good luck!
