Get the V6. I own a 2011 Terrain SLT-2, 30,000 miles, still getting 22 mpg w/V6.
The 4 cyl. will get about 22-25, but you'll lose resale value, and not be able to tow anything. EXCITING NEWS!!!! I am a GM Retiree, and we can "Tag" vehicles that are
"In Service/under Evaluation", and when they have 5,000 miles, we get them with as much as 20% off. I wanted to upgrade to a Terrain Denali, but they ONLY come in Black Interior, and all available to "Tag" were Black/Silver.
I TAGGED A '13 GMC TERRAIN DENALI IN GREEN METALLIC- LIGHT TITANIUM!! IF YOU GO TO "BUILD YOUR OWN", THIS IS IMPOSSIBLE!!! Either it is an Amazing.."One-of-One", or new colors for 2014!?!
Look at my Profile Pic, I found that ONE small pic on Google Images.
I have the "Tag" Sheet in .pdf, with VIN # and colors to prove it!!
