Although the best selling automobiles each year don't change by too much since trucks like the Ford F-150 and cars like the Toyota Camry are always at the top, there are some cars making the rounds of the popularity lists that might impact the end-of-year best seller lists. For example, the Hyundai Sonata is gaining a lot of ground in popularity in the sedan category. Once a decision to buy a new, popular car has been made, it's a good idea to stock items that will help keep your car in mint condition such as a windshield repair kit and a full tire replacement set of tools.
