I guess to clearify its the main big companies producing cars thoughout nascar history. For example Kia may be a subcompany of a bigger more important main manufactuer. You got 4 ford,toyota, chrysler, amc. Dodge/plymouth was more under the chrysler umbrella. You got 2 countries there are still others from past older years. The bonus is which brand/model and its more of a tidbit info of what the car of tomorrow is referred to Today.
