I watched the whole thing, such a great video !!
I would love to own an Alpina some day - watching the various processes done by all the Alpina technicians is a tribute to serious German craftsmanship.
And the back story of how he came from a family which manufactured typewriters, and then because of the founders passion for cars built Alpina into such a world-class and well known company for 'above and beyond' a standard BMW's is a very interesting aspect I didn't know about before watching the video - you should all watch it, it's very cool!
