Carvana has a little better seamless process. Is there a reason why VROOM was preferred?
My personal experience was carvana was usually the lowest offer I got out of those 3 (carvana/vroom/autonation). Towards the end they were a good $5,000-$6,000 lower than the offers I was getting from vroom/autonation.
I didn't love the idea of vroom taking my truck without paying me, so I was happy autonation ended up being the highest bidder. I did have to drive it 3 hours to them, but I left with a check that day.
