Thinking of painting my LE black...
 

is this just wrong or will it still hold it's prestigue even with a new color skeem?

What year limited are you talking about?

an 83, made the first year the limited came out.

83 isnt the first year of the limited edition. 79 and 80 had one with leather :)

I don't know I'm thinking of putting a TII drivline in my 83' LE. And a TII hood scoop with a Mariah air dam. Is that horrible? Even if it is I don't care what other people think lol.

I say go for it. Other than the wheels theres nothing special about 83 limiteds. I don't mean that in a negative way or anything, but its basically a 83 GS with 14" wheels and a "special" shade of silver. I have one that I'm using just for parts. So you might as well give a cool looking car some go power Importguy. That's good that you don't care what other people think, you shouldn't, your life will be a lot better if you dont :)
