You people do know that when VAG bought out Lamborghini, the company still existed... meaning lot's of the original Lambo guys were still kept - which is why the V12 is the italian one, and not a german derivative. Unlike Bugatti, in which the company literally folded, and VAG simply bought out the dead horse and gave it people.
IIRC, the man who headed VAG during the Bugatti purchased also criticised BMW for not holding on to the MG/Rover company.
From that respect, I think it goes to show how much more brains BMW AG has compared to VAG.
