Great looking car! Couple of the obvious things: clear corners, clear sidemarkers and I would recommend these parking lights: http://www.turnermotorsport.com/html/detai...RODUCT_ID=J3622
Those crystal clears look a lot more refined and sharp during the day. Of course, all this should be complete with white bulbs!
If you want to go with some nice looking headlights I would check out these: http://www.umnitza.com/product_info.php?cP...products_id=149
Umnitza makes some great products.
As far as intake, look no further than a Conforti Cold Air intake. I just got one in last week and it's great. Quick 1 hour install and you're set. Tuner sells it: http://www.turnermotorsport.com/html/detai..._ID=JCINTAKEE36
As far as exhaust, I just bought a UUC System U exhaust...I am picking up my car this afternoon, so I will tell you how it works out!
There are three main sites I would recommend for tunning parts: www.bavauto.com www.umnitza.com www.turnermotorsport.com
Good luck with your car man, BMW pride!!
