des do a search of my posts i posted a detail review of my drives with and without DH. I have it and love it. The GT is one of my favorite cars i have ever owned...just the the right mix of everything..but i must say not sure i would love it as much without DH. Lex is right you can't miss what you never had.....but it is a totally different driving machine with it..
