They were offered from 1990 to 1993, no more than a few hundred per year with declining numbers over the period. You should get a premium over an automatic but that isn't saying much as bad as the market is. 100k mile automatics have dipped under $10k for serious sellers. I would think you're looking at $12k-13k for a nice car. The stick shift premium would be more if it wasn't such an inelegant set up - long throw, dog leg shift pattern, heavy clutch and ridiculously short rear axle ratio. The car is 3,000 rpms at 60 mph. One needs ear plugs for highway driving. The 124 sticks are 2,000 rpms at 60 mph. The U.S. 129 SL stick has always had my vote as the biggest modern day screwup by Mercedes - not because it's so terrible but because it missed its potential so badly.
