W212 - Heated windshield wash system.
Heading to northern Minnesota for xmas, best antifreeze washer fluid I have found in Atlanta is only rated down to 0F but there is the very real possibility of where I am going to hit -10 to -20. Should I even hugely concern myself with finding the -35 stuff once I get further north? My stepfather was freaking out on me that I am going to have a cracked reservoir and cracked lines if I don't have the -35 stuff in the tank and lines. I don't think MB would design a car that a freeze of the lines and tank would immediately cause a huge repair bill, I had a old '99 Neon (the polar opposite of good engineering) freeze its tanks and lines up and everything was just fine once it was back in a non-frozen climate.
