This car was built in 1970 as a 1971 US chassis model, but with all the Alpina upgrades to the suspension, transmission, interior and gauges, and of course a 160 DIN HP engine with two Weber DCOE carbs. Being a US chassis car, it has the emissions compliance sticker in the engine compartment, and the Pan-Am pilot who imported the car had a friend at the port of Miami.
Report from BMW Archives:
The BMW 2002 US VIN 1676010 was manufactured on June 23rd, 1970 and delivered on July 2nd, 1970 to the BMW dealer Bovensiepen in Kaufbeuren. The original colour was Chamonix, paint code 085.
While Bovensiepen is known as ALPINA it was also a "normal" BMW dealer at the time so we cannot say if the just sold the car or modified it. It might be a good idea to ask the people at [email protected] if they know more.
Nevertheless we hope this information is helpful for you.
