Well, I have a '98 540i automatic with the sport package, which really just means it sits lower, (wish I would have gotten a 6 speed), it is Black on Black. I haven't done any performance mods, yet. It has 18x8 Voxx rims, 245/30R18 Goodyear Eagle F1 tires. I have put the 01+ headlights and tail lights on. The headlights are 12000K HID's (violet in color), I like them but they are not as bright as 8000K. The tail lights have smoked turn signal lenses and smoked reverse light lenses, and purple reverse lights. It has 30% tint covered by 5% tint all around and 30% on the windshield. (Makes it hard to see at night) I have 2 12" Alpine Type R subs powered by 2 Alpine 500 watt amps, which is considerably underpowered, and a 4 Farad Power Acoustik capacitor.

These are just blue turn signal bulbs
The angel eyes, you can see the driver's side led's look a little dim and there are two that are burnt out for some reason.
Can't really tell they're purple, camera makes them not look as good.
