I bought a Ram 4x4 crew cab one ton 2014 in 2015 for my car hauler. You will lose warranty on most if not all brands as the factories don't like them to cross border either way. GM Canada doesn't like reimbursing warranty $ to the US and vice versa. Also, as a car dealer I have brought down more than I could count over the years. If you find one as KFhunter says, that fits your budget it makes sense. Emission warranty is always good, I believe, just not standard warranty. Motor, trans, adjustments etc, not covered. You can buy an extended warranty which many dealers sell to solve the problem.
