Hello from Minnesota, which is nearly as cold as Fargo, or Siberia for that matter.
Make sure you have a fresh battery, the biggest CCA you can fit in there (there is room for a much larger battery than stock). Synthetic lubricants are a plus in very cold weather; Mobil One flows when dino oil turns to syrup. Make sure ignition is up to snuff, although the coilover packs on the VX eliminate much of the traditional issues with plug wires. Of course, make sure the coolant is good down to -40.
