Ours is the GMC Terrain which, except for the body style, is identical. We bought it new in 2010 and now have about 90K miles on it with about 20k being towed. Absolutely probably free in these past six years. Car still looks brand new and I have only change the tires and battery. Typically, I get overall mileage of about 25 with 33 - 35 on the highway (4 cyl of course), and with 185hp has sufficient power to climb steepest hills or pass others at will.
Ours is the top of the line (when it was new) and has all the bells and whistles. New ones have all the new electronic safety features that you will find on our 2015 Lexus.
Great little care with plenty of room inside, very comfortable and quiet.
I would assume the Equinox would be the same and get the same results.
Highly recommend.
