It is all a matter of opinion but you cannot leave out the original GT 350's, the Cobra R's and many of the Shelby/Rousch/ Saleen models.
Personally, I vote for the 2001 Bullitt.
You can guess why.
Been Mustang fan since I met Carrol Shelby in '64 and saw the GT350 prototype at the shop.Been driving them nearly everyday for the past 35 years.
Have owned about 8 Mustangs - mostly Fox bodies and newer.
Included was '89 "7-Up" convert, '95 Cobra, and two '01 Bullitts.
Bullitt #2064 is my...
