Mercedes W123 cars and W108 cars came with steel and alloy 15" wheels at
ET23 and 7.0-7.5 inches wide. The steel wheels will bolt onto a 2wd w/o much
fanfare. On top of that, they will accept a Jetta/Golf/Passat hubcap if you
do not want to look at the Mercedes hubcaps. Alloys wheels will require
longer bolts as often discussed here.

The common 8-hole Mercedes alloys that came on the later S-Class cars are
around ET59 -- way too much for 2wd or even Syncros. They are usually 16's
in that application. The same style came on C-Class and E-Class which were
usually ET37. To make this even more interesting, several companies made
8-hole knock-offs which were designed for the W123 cars. Those are ET23. How
do I know?
I have one set of each of the above wheels.
