I believe this is the first 2010 conversion for the 07-09 sedans anyone has done in the US... publicly.
My 2010 sedan was smashed by some drunk driver over night while parked, so it's in the middle of getting fixed. My 10 headlights are taking some time to arrive, so I needed to borrow my friends 2009 headlights so the shop can aligned everything and weld the bumper reinforcement into place.
I ended up letting him borrow my smashed 2010 headlights and my new bumper while we used his continue the work on my sedan.
I recovered the headlights, but they had several holes in the back, i fixed it and plastic welded it as much as I could, and we slapped them on his car.
Here's a teaser shot, I'll post more when I get home and upload pics off my camera.
Here's the info you guys should know if you want to do the conversion...
You will need:
Bumper Cover ($350 from the dealer)
3 lower grilles
Fog Lights ($160 a piece from the dealer)
