Go to NADA.com and look up the value for your area code. Also, look under the dash for signs of water or sand. Lots of Hurricane Harvey cars out there.
Thanks for NADA tip. I used KBB and other for sale listings to value my trade but Nada is way higher than both. Not sure why.
Been following these trucks for a while so I know they have been at the dealer forever. Plus I checked the carfax and shows they have had possession since summer 2016.
