Alpina B10 V8, E39, based on 540i. Restoration project is on-going. Claimed to be 347BHP and 450 Nm for the 4.6 V8. The Alpina documentation specific to the car, states 355BHP and 480 Nm. This car is from 2001, with extended Alpina leather, and 19″ classic wheels.
After two weeks of a detailed check-up at BMW Dubai (AED 4,000 or $1,100) plus my additional instructions, I came to understand that the core of this car is healthy. The only big mechanical aspects are: front wishbones, rear wheel bearings suspensions (Alpina specific, will cost a fortune as I want genuine OEM only), the rubber disc connecting the gearbox output to the prop-shaft, and the spinning crankshaft joint. Also the AC/dynamo belts and steering are weak.
