Any of the big three, they all make quality vehicles. I personally think the Chevrolet is the better one, then Ford, and Dodge. There are many factors to weigh, but I base my opinion solely on body integrity. This has been one of the major advantages of the foreign vehicles. It is kinda funny, when the Japanese vehicles first hit American soil they weren't much more than a sardine can with wheels, after a few years they were making better vehicles than the American products, today many automobile companies set their standards on the Lexus (A part of Toyota) and are using a better quality control to ensure a better vehicle.
Toyota and Nissan continue to build very good trucks, but American is catching up fast, go to the April issue of "Consumer Reports" and read the reliability information on all of them and I think you will agree.
While in the business, I challenged a potential new car/truck buyer to go drive every used vehicle he could find that was three years old, or older, and compare the different makers from that point of view. This is about the point when things start to fail, of course, use, and preventive maintenance play a big role in how well a vehicle holds up too, but it does provide a starting point to measure the vehicle's reliability and integrity.
