Probably not a situation you'd encounter in Florida but if you'd ever had to do a flying 35mph U-turn on 6 inches of snow to keep from hitting a train in less than 4 car lengths, you'd be damn glad you had a 4-M over an LSD. The LSD brakes 1 of the two drive wheels, the 4-M hydraulicly locks and drives all 4.

I don't think the 104 wins in the simplicity either. Mercedes first few attempts at EFI weren't exactly known as robust, where my 103's CIS can run with the control module disconnected. Everybody has an opinion but after 15 years working on them you can see what I park in my garage from my sig.

The people who drive like that are already all dead, hence the dearth of demand for 124 4-matics.
