I would not have shared this if I my self was totally surprised with the turn of events. My Mazda 3 lease was coming to an end in October. My original intention was to return it early so I can save couple of payments. But then I just casually browsed this forum to find out the deals people are getting. When I saw folks were selling their leased cars and making money out of it, I said let me try. Here is what I got for 2018 Mazda 3 with 15,000 miles on it.
Carmax offered me online $17,800 for the car, while Caravana, Vroom were in the $16K range. When I took my car to Carmax they said they will pay $18,000. Along with that they were also able to get a $700 off of the payoff that they passed on to me. I walked out with a check for $5,745. I am super happy with what I got as my original intent was to just save the two last payments.
