As someone who has 25+ years under his belt pulling wrenches I don't agree with you.
I have worked on just about every car made and can state without a doubt GM sucks compared to Toyota. The techs loved Toyotas when they came in, it was rare indeed that you had to do much to them besides regular services.
This administration has a history of attacking people from doctors, insurance companies, private citizens, Wall Street, etc.
The list is near endless, I have no doubt this is a ploy to help prop up Obamas union buddies running GM.
