The water drains built into the car are small and tend to clog easily.
Winter driving exacerbates this with the frozen slush that can built up on the body works.
If you put the car in a good hot water car wash with a full chassis wash and make sure it is dried throughout before exposing it to sub-freezing temps, it will last as long as if you were washing the car regularly at home.
The problem is often you can't was it often enough in these conditions.
In conditions that I have here now, that would mean putting the car into wash daily.
In addition, the open velocity stacks and screened jet covers on the Webers do not get along well with these types of car washes.
You have to get the rock salt off of everything. galvanic action with the steel and the salt in these conditions just accelerates corrosion. Even the polished stainless steel reacts with it to some extent and becomes dull as a result.
Also snow and ice do not get along well with these types of low profile, wide tread pattern tires.
What will get you through it well though is the original skinny tire configuration the car was delivered with, and probably the 7/8 inch wheels being the best overall compromise for all driving conditions?
Counting in my head, I come up with 6 people that I specifically knew who used their Panteras new as their only and every day cars, right here in the greater NYC area.
The cars are quite capable of very wintery use although you will never get the car clean again in all the cracks and crevices IMO.
