2003 2dr Coupe 305-horsepower 4.6L V8
5-speed manual RWD		 I see way too many of these things around. Most are the V6 variant which is just sad. I really feel like the wide variety of engines and packages dilutes the Mustang brand too much. I really think it is a poser car. see full Ford Mustang review
