you have to visit the dealership many times and get to know all salesman, before you decide who is going to "earn" your business. Remember, BMW always will refer you back to the person who sold you the car, so choose well.

now, I get to test drive alone any model as soon as it comes out, my sales rep (I picked) even calls me 2 days before they get delivery of any new models to see if I want to test drive it first. I like that... I've been buying from the same guy since 1992, so he's like family, and treats me like such. So I follow him to any dealership he goes.
