Wow, lot of posts since I got a chance to come back and check the thread.
Um, I think the Mach460 is more than enough, but if you're a sound guy, and like to spend/customize, by all means, do what you like, it'll be your car!
However, the comment about F-body. Honestly, they are a bit faster, especially at higher speeds (above 80mph especially), but, that's about it. The mustang is a far superior car overall, go look at any magazine comparison or notable website comparison ever done. The mustang won outright everytime. The mustang, single handedly ended the Camaro/Firebird, outselling them over 3/1 in their last year of production, that must mean something.
