After my ten years is the fleet service business that serviced thousands of vehicles every month of just about every brand, I can tell you our years of record show there is no significant difference from one brand to another. Every manufacturer is making great vehicles today. The only real difference is style and price. After a dozen Toyotas and Lexus, I personally no longer buy imports because they simply cost too much more than the domestics I now buy. I do not own a GM vehicle.
Toyota should be worried more about the Koreans than the US manufactures. They are the ones that compete with Toyota in more of the worlds growing markets. They are building great cars that sell for thousand less in those markets
