In Kingston, a mere snow flake has the trucks out burying the streets with an avalanche of salt; my car was winter driven here for 13 years and there is only a bit of surface rust underneath.

before getgting the '88 300e, i looked at a '95 cadilac; i looked underneath, and rust from arseh*le to appetite; then looked at the 300e, underneath, and what a difference

i asked the local mb tech about putting a block heater in, and he said a change to a lighter oil viscosity would suffice (5w30). however, the manual quite clearly states to install one where cold climate.

agree with above - cold start and drive with tlc. wash it regular like; deal with surface rust when it appears; some of the body parts collect crud, prevent water/ice from leaving and start to bubble up the area.
