This Coupe is currently located in Tucson, AZ.
I bought the car in Hawaii about a year and a half ago.
The previous owner didn't take great care of it but I've worked on it and fixed some of the more important things.

I'll start with the bad (mostly minor things) and if you are still interested after this then you can read the good.

-The passenger side rear quarter panel and rear bumper need to be repainted, I'm not sure if it's sun damage or defective paint but it needs attention. Been this way since I bought it.
-Small rust spots from ships exhaust (common in Hawaii)
-PO backed into something (very minor misaligned bumper)
-General minor dings/imperfections
-Someone tried to take apart the interior and broke some clips
-Normal wear on the interior
-Seat rocking/sliding issue (have poly bushing)
-Glovebox sag
-It's an automatic
-There are a few small things to be addressed mechanically
-Belt tensioner (maybe)
-Washer fluid pump/lines
-Issue with the DCS (research points to the yaw sensor, I have a spare)
-Needs an alignment
-Tire shops and PO have messed up the lips of the wheels (I never parallel park)
-Sub grille cracked
-General wear
-A couple roundells need to be replaced
-Only 1 key and it's beat up
-Oil filter housing gasket needs to be replaced (common issue)
-Rear Hatch lock actuator may be messed up
-This is all I can think of, will add more if I remember/discover anything.

So, now on to the good!
-It's a very rare build!
-Factory Sunroof Delete
-AC Works
-Oil change less than 100 miles ago with Mobil 1 Full synthetic 0W40 (recommended for BMWs)
-Obviously... the mileage... just over 48,000
-Supersprint exhaust. A previous owner bought the M Coupe set and returned the passenger side muffler. Drivers side was installed, sounds good but not too loud.
-Sony bluetooth headunit, the rest is stock Harmon Kardon
-If you've ever driven one then you know how much fun they are
-Almost the same HP/TQ as the S52
-Stewart water pump, new radiator
-Stainless steel brake lines (except the rear centers, but I have them)
-Drilled/Slotted rotors and Pagid Red pads
-Canadian DRL Relay
-Bentley manual for the Z3 will be included.
-Cosmo Racing strut bar.
-I have lots of old service records and receipts
-This is all I can think of, will add more if I remember/discover anything.

-Lots of extra parts (for the right price) These parts may be sold separately if you are interested.
-Set of 4 19" Braid wheels, black with silver lip three piece. Fronts are 8.5" (I think) and rears are 10". The Offset is designed for E36/E46 M3 and the M coupe but they will fit (just don't hit bumps going fast or they rub in the rear a little.
-Lots of suspension: Brand new set of Koni Yellow Sport rear shocks and front inserts (I know it's for the M Coupe) I also have a used set of the Koni Yellow Sports and a set of used M coupe stock suspension so you can install the new inserts into the strut housings. H&R Sport springs for the lowering of the car if you so choose. M Coupe front sway bar. Few extra sets of shock/strut mounts.
-Various little parts (rear handle gasket, the seat bushings, oil level sensor, yaw sensor, most of a cooling system, misc little clips, gaskets, grommets, thingys and whatchamacallits)
-Z3 Roadster car cover, high quality, can barely fit coupes if you remove the antenna (sold the roadster a while ago)
-Brand new set (never mounted) Sumitomo HTR Z II for the stock wheels, (225/45ZR17 and 245/40ZR17)

Most of what the car needs is little things, if you're willing to put some work into it you can get a lot out of it. I'd rather tell you as much as I can than have you get mad for being surprised when there is work to be done.
If you live near-ish to Tucson and need help, I may be able to deliver the extra parts. I can't drive all the way to Cali or New Mexico.

I'm willing to consider trades + at least $8,000 cash. I'm kinda picky on the trades though.
Some of what I would consider, in reasonable shape.
944, 928, 914
BMW E30, E36 (maybe other BMWs)
Manx
Vette (C3 or C4)
FJ60 or 80 Series Landcruiser
A nice Benz
If it isn't one of these then I'm probably not going to be interested, but you never know.
