Just take the front chevy badge bar off.
Looks a lot better.
There's two things you can do for the sedan headlights.
Joey mod. (Where you paint the chrome on the inside of the assembly, most paint it black, but I've seen people color match their car or completely different)
Halos. (I just ordered these 3 days ago, will be here in a couple days.)
As for the tail lights, there are no aftermarket options for the sedan.. sucks.. You could tint them though.
I have H&R springs on my 06 sedan. They ride pretty good, they started settling in a couple weeks, lowered 1.5inches.
I wouldn't get any bigger than 205/45(or40)/16 wheels
My 205/40/17 rub ALOT (If you get lowering springs)
They have eibach springs too, but I've not had any first person experience with those.
If you don't have em, fog lights make it look pretty good.
Some HID's
Tint
Sound system
Don't know what else..
What part of NWA you in? I use to live in lowell for a bit.
