I had to sell my Mustang because of back problems. The estimates I got from Vroom, CarMax and Carvana were unacceptable for a 2018 GT premium convertible with 18k miles. The same is true of the trade-in value I was offered. WeBuyAnyCar gave me $5k more than the best of the other offers. I was very skeptical, but it was as easy as they advertised. Just an FYI.
