May be my question is very confusing

. So let me elucidate it better!
My research is focused on understanding the lifestyles and attitudes of US car buyers. My preliminary findings found that there are some 6-7 'types' of car brands in US. These car brands cater to different customer segments. Now I want help in defining these customer segments in terms of their habits, attitudes, lifestyles (such as what brands to they drink, where do they eat from regularly etc.).
I will write below the 'types' of car brands I identified:
1. BMW
2. Subaru
3. Mercury
4. Honda
5. Chevrolet
6. VW
7. Dodge Ram
So please pour in your ideas and opinions. It will go a long way in helping me gather insights about US car culture.
