The GMC Acadia competes in the increasingly crowded mid-sized crossover segment.. This SUV is going to fly off the lot. Come see it while it lasts! There's nothing like a sunroof on a sunny day! Great fuel economy (EPA estimated 21 MPG combined) to fit perfectly into your budget. The rear camera makes backing up a breeze. You'll also love this vehicle's keyless entry, tinted windows, a cabin air filtration system, extremely convenient cruise control and low tire pressure warning.
