Ford dealer offered $26,400 for my 2013 ridgeline sport, 33,400 miles. Looking at a 2016 f150 lariat crewcab, they were discounting the f150 $6500. I was impressed with the amount offered on my trade. Only thing keeping me from buying was the length of the f150, 25 inches longer than the ridgeline. If i remember correctly my 13 sport rl listed for $30,830. That amount of depreciation is great in my book.
I'm very pleased with how well the Ridgelines are holding up on the secondary market. The Subaru Baja I sold to buy the RL was the same way. Both are extremely useful vehicles that didn't exactly sell like gangbusters, but they fetch a premium used.
