I tried to sell a very nice full size GMC Sierra 4WD. 2012, so older, but only had 75,000 miles on it.
KBB told me it was worth about 19500.
I listed it on Facebook and craigslist.
I got about 5 "weak" offers on Facebook, for between 15k and 16.5k. I had said "I'll take as low as 17.5k".
Craigslist was even worse, i got scammed by somebody who asked for a title report. Then sent me to a website to get one. Their website was buggy, and I figured it out before any damage was done.
A friend of mine referred me to carvana. I got on their website and they offered me 20,200 ish. And I had them lined up to come pick up. I ended up canceling at the last minute because of personal reasons, and rescheduled a week later. I had to start the process over from scratch, and guess what...They offered me 21,100ish.
The best part was, they drove a flat bed to my house, picked it up, and the whole thing took me about 15 minutes.
So, before I got way down the rabbit hole of a private sell, maybe get a quick estimate from carvana or similar website.
