Broke Down

We have 3 trucks, and 2 cars sitting in our yard. They are all broke down. I limped the old Ford truck home today. I can't get it figured out. It don't matter if their new or old all our vehicles seem to be broke down. It doens't seem to matter that we change the oil regularly, give them tune ups, replace old hoses, tires, and other almost wore out parts. What ever we don't think about is the part that gives up and says it isn't going to let the car or truck continue to get us from point A to point B. Thats all we ask. Just to go from home to job and back. We don't have anything fancy and don't want it as it will just brake down.
Does everyone have this problem with their vehicles? It seems so. Which leads me to beleive that it might be a manufactoring problem. Another words poor quality control.
