Eric, you know what i think non M cars came with a getrag, and M cars came with ZF, i was looking briefly in the bently book but im not really sure im not at home so i cant check.I just did the whole inspection II service at home and i also remember reading about the issues with the late model M's and i also read that they were being replaced and not fixed. But i thought there was a related issue aside from the oem issue, with those with aftermarket shift knobs that were too heavy , i thought it was bushing related. I know someone out there can repair M3 ZF's, its not rocket science, heck there's only 2 places that i know in the states that repair and replace individual parts from the Getrag 6 speeds from the Supra, and they are reputable dealers that deal with after market support and are sponsors for some toyota teams. And those that had them repaired , (syncros,gears,seals,bushings) never ever had issues. It can be done, just have to find somone whose done it.
I don't see why this ZF is so "special". I bet you someone out there has cracked open the tranny and had it fixed.
