GM can have all the horsepower they want but in reality they aren't that much faster if faster at all and don't turn half as many heads as the Mustangs. As for V6's go the Mustang base coupe is more affordible and faster anyway than a GM base coupe.(I proved that today on the street when I smoked a Camaro V6;same year and same mods)The other nice fact is that there are way more performance parts out there for V6 Mustangs than the GM 6s. The Mustang is definately a good buy and a sure way to go.
Six-disc in dash and high output sound system, leather seats and steering wheel, Rear window de-fogger, premium five-spoke alloy wheels.
It needs more power. A 7psi supercharger will do enough to keep up with the V8s.
