There was also a Special Edition AMG w124 e320 Cabriolet that was an option in Europe for 1994 and 1995. I believe that only a couple of hundred were ever produced.

The car had uprated suspension, wheels and a body-kit, plus the m104 had about 35hp over the US version,,, but I don't know if that was just the regular Euro-spec engine or some AMG tuning.
