They only compare ‘new’ models, so any tried-and-true vehicle is not in the running. And if there are no new models from Toyota and Nissan, or ‘new’ models from Ram, Ford, no real competition. Rigged voting.
The 2015 Nissan Frontier looks exactly like the 2006 Frontier. I think the Taco is relatively unchanged for 2015 as well. Although I’ve not had time to see one yet. So yes, the Colorado is a new look in mid-size trucks. But only game in town in that dept.
