That's NIX V12 under a lot of snow - many more pictures coming soon.

Here's my Black 1991 BMW 750iL, also known as NIX V12. I bought it on eBay in January of 2003 for about $7000 (compare to retail price when new - ~$80,000 :)). It should be noted that pretty much everything added to this car was bought on eBay as well - I like eBay a lot.

No performance upgrades (I figured it was powerful enough as it is) - I focused on the sound system and inexpensive interior and exterior touches.

Sound system features:
-stock component speakers in the front and the rear, except the front tweeters were replaced by MB Quart tweeters
-Sony Xplod headunit (eBay, ~$150)
-Pyle Eternal PLA2370 2-channel 1400W amp for the subwoofers (eBay, ~$100)
-2X 12" 700W Q-Power chromed subwoofers in a bandpass box with a plexiglass side (eBay, ~$150)

Exterior mods:
-got new BMW emblems for trunk and hood (were faded) (eBay, $10)
-tinted windows (were tinted when I got the car)
-chrome grill kit (eBay, $25)
-chrome "V12" emblem on left rear side (comes from a Mercedes) (eBay, $20)
-(coming soon hopefully) carbon fiber on all blue parts of BMW logos
-(coming soon maaaybe) chrome door handle covers

Interior mods:
-(coming soon hopefully) some FatMat applied to trunk to dampen subwoofer rattles
-(coming soon hopefully) carbon fiber vinyl to cover up all woodgrain interior trim
