ok i have a 2002 alero 4 dr, and i was wondering if anyone could tell me in detail how to get the old carpet out and get the new carpet in

ya need to rip apart the entire inerior of your car
center concloe seats 1/4 trim
everything to make it easier on you
have fun

yea its really basic, just pulle the seats out, all the floor trim panels..your center console, and have a sharp knife handy
