As if the SLS AMG wasn’t bad (meaning good) enough, Mercedes-Benz now ups the ante with the 2013 SLS AMG GT, a 583HP-packing beast that does 0-60 time in 3.6 seconds and maxes out at a brisk 197 miles per hour. Not interested in the speed? Riiight. We’ll play along. Let’s see, there’s the 19-inch alloy wheels up front, with 20s in the back; optional leather with contrast stitching and a diamond quilt pattern on the seats and doors; and Bang & Olufsen sound system. Not interested in the speed…  pssht.
