you have to pay sales tax when you buy parts at a dealership in California. what is the sales tax rate in marin county now?
EVERY time i have bought parts from a dealership (usually an emergency) in Sac, either Niello or Roseville, i can't believe their parts departments stay in business. compared to the prices i get from fap99 or blunt, they aren't even in the same ballpark.
i just bought a factory e30 windshield and seal from blunt and paid over $100 less than the price i got from the dealer, even with the dealer's bmwcca "discount".
