i officially offered my "services" on this board before, no real identification needed, most people know it.
like i mentioned to you ALPINA sees itself as a car manufacturer and not a tuner. that means most power-train related parts can not be purchased without proof of ALPINA car ownership and a valid reason for the need of the replacement part in question. and that's only for customers overseas that can't bring the car to ALPINA. used parts are still a good alternative, even though some folks ask stupid amounts for them because of the above fact.
