This new Mustang has my attention, the best body style I think I've ever seen. I don't want to spend $90,000+ on some of these top shelf GT350R's, but want a car that will keep up or beat my M3, (which isn't supercharged) and other fast cars where I live. I don't track my cars. So I'm looking for opinions from guys who know these (sixth generation) cars on what you think would be the best bang for the buck. Only interested in the 5.0 L "Coyote" V8 or 5.2 L "Voodoo" V8 car. Shelby, Roush, GT, etc. Should I get a stage 3 car straight from the factory or mod it myself? Let me have it and thanks!
