RC:

Forgot the most important thing, guys: When I saw the SLS at my dealer, I noticed a new Mercedes S class with AMG exhaust but no model designation on the rear. The mechanic was just starting the car and then drove away slowly. Amazing sound and yes, it was a turbo ("my guy" confirmed it, not saying which AMG model this was). So it can be done, which brings me back to my X5 M and BMW, wondering why the heck they couldn't achieve a better exhaust/engine sound. 

 

What an amazing dealership Smiley
