It's slated to built through year 2023. Diesels are not designed to be fast they're designed to be strong. They historically have always brought more at resale then a gas version of the same vehicle. I am curios as to what type of driving you do. For the most part if you short hop all the time the mileage will almost be no different then any other vehicle. If you cruise on the hwy then it will do well. I typically get at 70mph about 33mpg and at 80 about 28. Are your numbers within that range?As I follow up, since the Colorado diesel looks to be discontinued after 2020, do folks think that will be better or worse on re-sale values?
