Beautiful ride. The Competition wheels look amazing on your ride.
Definitely agree with the LCI trunk. A good price for a used one will be tough but getting a new one is not too bad. DDM has them for less than $500. And of course you can also go LCI +CSL-style from VIS for $750.
A cheaper alternative is getting the all red LCI-style pre-facelift lights. I've seen these in person on an 2007 E90 and it looked fantastic, confused me at first.
