Carvana is great. We sold them my wife's 7 year old minivan with 70,000 miles on it for $19,000. That was $4,500 more than the dealer offered on trade-in. They made it super easy too. Won't work with a Tesla lease though. If you own it outright it will, but not if you leased it from Tesla (vs a third party finance company).Or just do carvana. That service is crazy convenient they literally show up take the car and hand you a check. That was my preference but the system couldn’t figure out how to value a model s for whatever reason, and no one would return outreach. I have used it for other cars - fantastic.
