I saw that no one has put much in the Taurus section, so I figured I'd start off. I have a Silver '98 Taurus SE with the 24v Duratec Engine. My current mods include: Hella Optilux 1500 Fog Lights, K&N Panel Air Filter, Blue Turn Sigs, Bluish Headlight Bulbs, and not a bad system (2 10" Sony Xplod Subs running off an Alpine T-406 Amp). Features on the car when we bought it were: Leather, Sunroof, Mach Audio, Clarion 6-Disc Changer, Alum. Wheels, Dual Exhaust, and of course it's a floor-shift tranny.
I've got some pics that I will post as soon as they are developed.
Hope to hear about some of your cars....
