My 89 240sx was purchased primarily for winter driving, and she does it quite well.
Heres a lil tid bit for you all. You pretty much HAVE to use a block heater here in the winter because temps reach -50 F no problem where I live.
Well last winter when I first got the 240sx I used to plug her in all the time. She started up everytime as well, no probs. Anyways when working on her over the summer months I found out the plug to the block heater was never actually plugged into the block itself!
It was jarred loose, which only proved my assumption correct that it wasn't working in the winter because I could never hear it start up once plugged it. (kinda sounds like a kettle starting to boil water on the stove for those who never used one)
Nissans are tough....
