+1 for louvers
-1000 for xenon
when I bought my mustang it had a sh*ty xenon body kit and I quickly ripped it off, their stuff is garbage... xenon ftl

 

here are a couple pics of them...

I personally love them... Dont listen to other people if you like the look its your car man. As long as there isn't all sorts of tacked on crap they look good professionally painted and installed. Take them to a good body shop with pictures and they will do it right.
