This is simply a general question about the new model Colorado's and Canyon. I have been contemplating buying a new Colorado with the turbo diesel. Because they are in such high demand, I have yet been able to find a dealership that has a demonstrator with a diesel powered engine that I can test drive. I currently own a 2008 Suburban which has been a very reliable vehicle. So, the above sad, does anyone who owns a Colorado or Canyon had any problems with their truck that I should keep an eye out for in the event I can find the specific Colorado or Canyon. Beings there are no current discounts on them I will be waiting until there are to buy one. But, until then, I would appreciate any idea on what to watch for either body our mechanical wise. Thanks.
