Tried selling to Algo. They gave me a price online, then after the video call the price fell by 3K because of a small scratch. Don't fall for the initial quote they give you.
It probably didn't fall because of the scratch. They lowered it because their website is just to get in to talk to them right now.
They did this on cars with no damage at all and claimed that the system doesn't take the current market selling into account.
Either way, get the quotes from the other sites and negotiate them all against each other.
I have had sales to Algo, Carvana and Vroom. All were successful.
