duly amended.
it appears that there are limited choices for the gen II SEC's, because of the smaller offset.
Are there any other mers that can fit straight on, or are spacers my only option?
You'll need wheels with a low offset, so be careful.
The AMG alloys Aero I alloys at 17" x 8" have an offset of ET11 for the W126. These also came with an ET28 offset to fit the W124...make sure you find a set that fit as they are few or far between.
