It depends what your goals are for the car. Although, I really like the CDC classic chin spoiler
on these S197 Mustangs. I feel there's something missing on the front bumper with out a little extra material.
That being said, I'm also completely for performance! My very first car was in dyer need of paint, yet I installed Heads, Cam, Intake, and a built rear first... So it's easy to say where my main focus lines.
Bottom line, it depends on your personal goals. If you're looking for more style right now, then I say go for it!
