Pros
Work life balance isn't bad, nice offices, good place to learn since it has a flat organizational structure.
Cons
Very little to no room for advancement. Promotions are very hard to come by, especially going from a normal employee to a manager. Lateral movement is possible, but for no raise in pay. They'd rather higher someone from BMW, MB or the corporate office in the UK than promote internally. This causes low morale, but HR doesn't care, since they are basically useless. Raises and bonuses are abysmal. Like not even equal to cost of living. No summer hours. Don't even think about asking to drive a company car. Management thinks they are made out of gold. The parking lot is full of cars literally rusting away, but they won't let you near them. What good is it working for a car company if you can't even drive them? US management isn't bad, but they are stuck with the horrible decisions that are made in the UK. The UK management is basically running the company into the ground. IT sucks and they don't invest a dime into technology. Reporting is non-existent in many cases and work-arounds are the rule not the exception.
