The only thing that I can think of that is specific to a W124 coupe is the articulating seat belt extenders. For that matter, the W124 cabriolet's have them, as well as W126 SEC's.

Other than that, the checklist would be the same as any other W124.

BTW, what year 300CE are you considering?

The early 300CE's have the M103 engine (if I remember correctly).

I think 1990-1992 300CE's got the early 3.0 liter version of the M104 engine. It still used the old CIS-E fuel injection, with a distributor and spark plug wires. It did not have variable valve timing, either.

In 1993, the 300CE got the 3.2 liter M104 engine, but the badge wasn't changed.

In 1994, the same 3.2 liter engine continued, and the badge changed to E320.
