Came across this in a few places reading specs on the Boss (including Ford's) and it says the 2013 HAS the Hill holder feature built in. Honestly since Im pretty good on the clutch Ive never noticed it. Saw this reference that how it works is discribed in the Mustang owners manuel...." You can find this topic discussed on page 166 of the Mustang Owner's guide (2nd printing) you get with your car." Didn't get a chance to check that out as car is under cover now for winter. I knew the new GTs had this feature, but didnt think that the Boss's did. Anyone else know this? If so, how DOES it work exactly.
