I've had this car since I was 16 and added a few things to it.

Clear corner tail lights
Clear corner park lights
HID fog lights
AC Schnitzer pedals, shift knob and park brake
Limo Tint all around
Alpine CDA 9827A receiver
Kicker L7 12" with an Audiobahn 8000T pushing about 800wattsRMS
Built in Valentine ONE radar system in the grill (posting pics soon)
AFE High Flow Air Intake
Software Chip from Bavarian Auto
Kaizer Strip 18" chrome wheels with bullshit Kumhos 225/40/18 front and 245/40/18 rear (sine I tore my Mich Pilot Sports apart after paying over 1200 for them...)

Future Mods
Full Flow Exhaust
I am thinking about the AC Schnitzer 19s in chrome (kinda expensive)
Flip out LCD by Alpine
Change headers
AC Schnitzer front lip
AC Schnitzer spolier/spolier above rear windshield
