I've got a base LE 2006 Camry. I've always liked the factory ground effects kit, but since I didn't order mine with it I figured it would be next to impossible to get. I've seen very few SE editions with it and know that it was a $1200 extra... so it's not very common. I can count on 1 hand how many I've seen here in Nashville and one of those was an out of state car.
Much to my surprise I found a car dealership that was selling the kit and it was even molded in my color. I didn't really want to pay a body shop to put it on so I read the instructions a couple of times, borrowed a drill, and jumped in feet first. Finally finished it.
