Parts site
 

Just stumbled upon this site
There's some alright stuff on here. Looked at the e36 section. They've got an alternative to the ///M3 mirrors. Kinda look like the e46 ///M mirrors. They have a rep. M3 rear diffuser for the non-M bumper and a few other things like chrome trim (if your into that) for your switches, ash trays and cluster etc...
