hey if you like GM then buy GM. Its your money and its a free country.
I want to like GM but have had very bad luck with them. I also strongly dislike supporting the union which pushes socialism in America.
The primary benefits from buying GM are linked to lifetime maintenance costs. GM has a very reasonable parts pricing schedule as opposed to the rice burners and German rigs. The replacement parts, and thus the insurance costs are lower and over the lifetime of the car or truck which BTW has as good as the Japs, the costs are substantially lower.
The jap cars have throwaway engines. A stinkin fuel pump or tail light costs a fortune! Plus they ride like a rock.
You buy whatever you like. I would not even consider anything else and I have owned them all.
