In the United States, the majority of households have access to or regularly use one vehicle. This is important because it shows just how included our vehicles are in our daily lives.
Looking at what people tend to put off the most, it appears that people don't fix the easiest things to maintain on their vehicles. This is because most people tend to believe that regular maintenance isn't that important, and can wait until the next time they bring it into the shop.
While paying a trained technitian may be your safest bet for more difficult repairs, the price of labor is extremely high in the automotive market. Still, Americans pay higher prices for easy-to-fix problems that could be done at home.
Cars are expensive commodities that most Americans need, so it's important that these vehicles remain effective for a long period of time.
