My CS has 400hp sounds great, but doesnt look very good from closer than 20ft, rather than display mine outside the showroom, i'd like to have my car in a Ford mustang commercial. The sound roaring out of my GTCS would definitely bring interest to the new california special.
As a side note:
I was driving next to this 1967 Shelby GT500 yesterday on Ventura Blvd. (Not as loud as my car.)
