Tough Choice...Looking for Advice

I'm looking to buy either a Mustang, Camaro, or Trans Am, from a model year somewhere between 1999 and 2004. I've always been a big fan of American "muscle" (I'm aware that none of these are muscle cars in the strictest technical definition, but run with me here) and now that I am buying my first car on my own, I want one of these three. Gas proces mean nothing to me, so my requirements of these cars are that they have a v8 and manual trans.

I don't want to hear anyone telling me to buy something Japanese or Korean, I'm flat out not interested.

Beyond that, any advice is appreciated! Thanks!
