Not sure why MBUSA won't allow customers to spec the GLS 450 with the AMG package. It's a really dumb decision IMO. They should also think about GLS 500 with the 429hp I6 from the 53 and Euro S500 as a bridge between over the big gap between the 450 and the 580.

It eventually will. My guess: those who really want an amg pack will be "forced" to step up to the 580. Once sales plateau/slow down, then you'll see 6cyl models in amg bits.
