I've converted my car over for track use and no longer need these seats. They've spent the last 6 months under plastic in my basement or sitting in my living room while I've been trying to sell them, and it's time for them to go. They're in decent condition, showing some staining and wear, but nothing too serious. They do come with the sliders and mounting, of course, as well as the trim that came out with them.
Update: I hit 'em with some cleaner and a paper towel, and they came out much cleaner. Most of the discoloration either went away or faded a lot, so they look much nicer now. The only real sign of wear is on the driver's side outboard, which shows some creasing and wear. (See the two closeup shots for the bolster wear.) Otherwise, these seats are in pretty darn good shape.
These seats are the "comfort" version of the seat, as differentiated primarily from the sport seats by their lack of "shoulder wings." They are also mostly electrically adjustable, and the car has memory buttons. The lumbar support is manual. They do not (to my knowledge) have seat heaters. I believe these will fit any 996 or 997, but will require some effort to make work in any car older than '99.
I live in Gaithersburg, and you're going to have to come pick them up, sorry. If I got really creative, I might be able to fit one at a time into my BMW, so if you're willing to take two trips, I'd meet you halfway somewhere, perhaps.
Let me know if you have any questions.
Thanks!
Dan
