I would detail the car like I was going to sell it myself and take pictures of everything. Later if they "find" some fault with it you have proof you gave them what they paid for. Second step would be take the money and run like a bandit because Carvana still hasn't turned a profit in the past 4 years. They keep overpaying for cars.
Amazon didn't turn a profit for many, many years- while AMZN stock rocketed. I read a blog for a few years (2006-2009) from a forensic accountant from India stating AMZN books were fraud and cooked using generally accepted accounting principals (GAAP). It didn't matter, AMZN was able to borrow money at near zero percent interest, grow, build any business they wanted to. And now that AMZN has achieved critical mass, they have made competing against them on a MACRO level very tough, and AMZN can turn a profit any quarter they CHOOSE to, for as much profit they want to. They may not be able to increase revenues per quarter at will, but they can turn any profit they want to for a few quarters.
Why is this relevant to Carvana? Carvana center of gravity is not retail used vehicle sales. Carvana's center of gravity is in the financial services businesses. Their two primary financial services business is selling bonds (full of vehicle loans), and servicing vehicle loans at which they get a fee for every loan, every month they service the loan. And of course financial service businesses also make "killings" on late fees, bounced check fees, etc.
Carvana does not need to sell a used vehicle to an individual at a profit to achieve its goals. For Carvana to achieve its goals, it needs to acquire thousands of car loans every month, and package and then sell the loans. And the terms of the loan sales is that Carvana gets to service the loans its sells.
Overpaying for cars may allow Carvana to achieve its corporate mission of selling bonds filled with vehicle loans.
