I am starting a search for a 1995 E420 which will be driven in Nebraska. In the past I have installed snow tires on all 4 wheels for the winter season. Does any one have first hand experience with the 1995 era E420 in snow and with or without the ASR slip control option? I am afraid that even with snow tires, this model might not go too well in snow without the ASR option. On the other hand, can the ASR option be partially disabled like the newer models? I assume the performance would be better on dry roads without the ASR kicking in.
