Autotrader is just about worthless. Those prices are just if you qualify for a million rebates.
Since I'm not a vet, farmer, rodeo winner, that's an FFA, AARP, AAA, VFW member I don't qualify.
Ebay once in awhile has some legit deals. There was a leftover Big Horn on their in March for $32k I should have pulled the trigger on. The color was an odd light green. Looked like a special order the dealer got stuck with.
Another dealer had slightly hail damaged All Star Silverado's for like $26k.
If your willing to travel and poke on ebay for a few months you can score a decent buy it now deal.
