Can you negotiate with Carvana when selling your car?

Carvana does not negotiate in the traditional sense. They make an offer and you accept or decline. You can submit additional documentation like service records or comparable sales data and ask if that changes their assessment, but there is no back-and-forth price negotiation like you might have with a dealer. The most effective way to get a better number is not to negotiate with Carvana but to get competing offers from other buyers first, so you know whether Carvana's number is worth accepting.
