Why would it matter???
I am 100% serious- There is nothing about buying a car that you can leave to the integrity of a car dealership employee. Sure, many are great- but the risk of having one mess up and cost you dearly is enough that you simply cannot take anything on faith.
What are you looking to do?
I will say my IMPRESSION in some of these "its the only BMW dealer in the state" places, is that they fall way short on anything but selling a new car at $500 under MSRP. just an impression, I am sure 10 people will say Mr. Herrin is their kids' godfather.
