Let me know when you go! I know exactly where you're talking about and this would certainly be fun! I've done this both up and down the front side, and have also been down the back side. A good alternative would be SR78 down Banner Grade on the other side of Julian.As a matter of fact, downshifting the S65 when being driven aggressively on the Stelvio was pretty cool. It's almost like BMW miniaturized a racing driver and put him in the computer for those folks who never learned how to heel-and-toe a manual transmission, just so they could have the experience. I wouldn't mind standing by the side of the road to hear it from outside. I may do just that when the car bet's back to SoCal. Therre's a well-known run up a certain mountain in San Diego County that would provide an ideal venue...
BTW: Excellent color choice! It was my wife's choice, but I really love LMB!
