Maxima would be FWD, I assume.
If you worry about RWD in snow, then you'll have problems.
Charger has available AWD, if you have your heart set on that vehicle.
I assume lo4 is some kind of slang, or a typo, for 4 lo, which is low range four wheel drive, which would be found in a standard 4wD vehicle such as my Cherokee.
I now own an AWD, and a 4WD, and never going back to 2wD.
