I did go for a '96 E300, 210.020. Very nice car. Mine just cut out on me while driving, but I think it's the K40 relay module. The joys of electronics.

The 210 drives far better than the 123 could ever hope. More power too, even without a turbocharger, and noticably better fuel milage.

Edited to add: If they're the same price, the 123 is grossly overpriced or the 210 is underpriced. I guess the former. People think they can get a ton of money for the 123. That's great until you get hit and the insurance company just won't believe you.
