Yes, too low. They want to buy at bottom dollar to jack the price up to ~$13k.If you have a CarMax within reasonable distance check how much they will give you. Get your best price possible for the minivan then ask them if they can match the CarMax offer, (if it’s higher which I suspect it will be).
I just bought a 2012 with 78k miles for ~13k from CARVANA and I will never buy from CARVANA again. I really wanted the one we bought because it was black and had a body kit that I did not want to pay aftermarket for… also, it was the only one I could convince my wife she wanted instead of a fu##ing Mini Cooper or stupid Fiat LOL
