The IS

Do you still have this car? Your mod list is basically identical to what my car has.

Mine is also a 2002 black L-Sportline with SRT intake, headers, exhaust as well. Mine also has the exact same sidemarkers in the bumpers. It is a factory manual+LSD. If yours was manual+LSD and you don't have it anymore, I might have your old car now lol.

It recently got brand new Fortune Auto 510 coilovers and black housing headlights before I bought it. It needs some tightening up in the front suspension bushings and it feels (and looks) like it's definitely been drifted on track by a previous owner. I'll just clean it up and daily it.
