Lumina Modifications!!!

Hi, i have some questions, i hope somebody can give me some ideas.

I want to change the interior color, so i figure that i can paint the plastic items, but the dash cover, i think i can take it out and stick some carpet to it... the floor is piece of cake on carpeting, and the ceiling cover will be easy. I jus wonder about the seats... i've been thinking if is worth it to change the cloth of the seats, or buy some other lumina seats, and wich seats will fit on it. i'll apreciate any suggestion.

Red/Marron interior going on Black/Gray...

Thank you.

oh, man, thats a big job. Hmmmm, Id just go to the junkyard, and find one with a red interior, and salvage what I could.
