I found a web site with movies with story line created by BMW. It was known that each movie cost $1 million for BMW to make for advertising purposes. They will be out for public purchase this Fall, but why wait when you can see it now.
When you get onto the web site, click on "Films" section on top and select "Ambush" which features the E38, then click on "View Film"
The movie include high speed chase and stunt driving of the E38. The movie with E65 will also be out soon. The other movies features the M5 and much more.
Check it out.
