chronodeco,

What are your RPMs at 70MPH? With your CE. Next time I'm on the freeway and have a clear stretch, I'll read my numbers at 70, to compare.

Have been out of town the past few weeks. A nice vacation to Hawai'i. Lots of nice W124 cars there. Anyway, last night I ran out my '89 CE on the freeway to check the RPMs at 70MPH. The tachometer registered either 3050 or 3100 RPMs (difficult to tell exactly which) at a constant, cruise controlled 70MPH. So . . . doesn't seem to be any difference between '88 or '89 CEs and post '89 CEs, at least at 70MPH.
