It was 0* this morning and I had to take the Z out of hibernation, and drive it to work because the drivers side lock froze on my beater. When I went to get in from the passenger side, the locking mechanism that catches onto the door bolt froze in the "open" position and the door wouldnt stay closed. Good times, good times...
Do what you feel is right, because at the end of the day nobody else gives a shit.
