hmm this sounds much more normal... there was a post from a bunch of Californians embracing the colder weather, claiming their N54s/N55s are breathing easier and enjoying the drop in temperature..
I always thought cars ran best in warm weather, not too hot like 95+, but from say 65-85 degrees..? Really did not think they enjoyed the cold. It's obvious here though that sub freezing temperatures are no good for everybody..
