I have a mint oem Monaco blue rear bumper and this m-tech/performance diffusor setup is exactly what I am looking for. Unfortunately I am located on the east coast. Consider shipping. I'll pay to ship mine, you pay to ship yours. Monaco blue is an awesome color, but it is a little rare. Please think about shipping, I really want this bumper. Good luck with the sale anyhow.
EDIT: I am actually looking for the whole body kit and it may be better in the end for me to just get it all together so I can install it together and so I woudn't have to pay individual shipping so count me out. Sorry! Good luck. Your car looks sweet.
