"Z" it's pretty much the same here too.(maybe not car wash prices) Anytime you mention BMW the price goes up. Calling around for G/Fs AC recharge (I'm too f'ckg lazy to work on her crap) her car and mine use the exact amount of R134 freon but they wanted $75 more for a BMW..
Hell my guages & evac system didn't cost that much and R134 freon is the same $ no matter what car it's going in. I ended up doing the AC on her car after that quote. "Just another place I won't EVER do business with"
