Money money money money, money!! Seriously though. Difference is power and trackability. And the name of course. A Shelby is a collectible. The Boss name also deserves respect and carries a nostalgia factor and thus also could be a collector's car. Shelby GT500 is a supercharged 5.4L V8. I don't know the hp number exactly. 550ish maybe. Boss is a modified 5.0 from regular GT that does 440ish. It also has upgraded suspension. It's not a daily driver. More of a track car. The "regular" mustang you speak of would be the 3.7 liter V6 305 hp. GT is a V8 412 hp. Difference there would be if course price, as well as power, sound, and gas mileage. Physically, or rather aesthetically, the v6 and gt are identical minus a different grill and some badging.
