The market varies greatly and we’ve discussed that on a few build so far. I was offered 18k for mine but declined. It’s fairly modded as well. I took it off the market and decided to keep it but another couple of weeks may have netted 20k. And just to note, I have way over 20k into it.
The market as a whole hasn’t really nailed down MJ prices. Many pick up there trucks dirt cheap and others are willing to pay. When I was trying to find a nice MJ about 5 or so years ago, most the ones I liked were in the 10-13k range. Ultimately it all comes down to finding the right buyer.
