I have owned this car for over 1 year so I have driven this car in all 4 seasons in Canada (f/w/s/s) with
(w) inter as the worst season so I will discuss my experience for this reason:
A) With windchill temperatures below -20^C/0^F highway driving becomes a challenge as the windows, esp. at the back, become frost covered on the inside even with heater on maximum level. I try to rub it off at traffic breaks, but it just freezes over again! Arrggghhh!!
B) I had to keep a sweater, jacket and gloves on while driving at 100km/h or 60mph on the highway even with the heater on maximum.
Reliable: Despite the window frosting on the windows, I was impressed with how reliable this car was especially for its age (1994) and when I park outside daily at temperatures below -20^C/ 0^F. The car started up without ever stalling or required restarting.
Great MPG: I used this to commute to work 70km round trip Mon-Fri on the highway. With a full tank Monday morning, I usually refill it by Thursday evening or Friday afternoon so it lasts about a week of highway driving.
Sounds like you need a Lada for that cold weather :-) Heating is not great in Japanese, but air con is pretty good.
