There is a line between BMW, Mercedes, Audi, VW | Porsche, they are a sports car company they are like a Ferarri or a Lambo.
Regarding that TP episode that was bull it was pouring rain, no full rear drive BMW does good in the rain, and mostly the M6 BMW, no traction control either! If they took it on their track it would kill it (in the dry), hey on their board the M5 beat the 911 GT3 by a second!
