That I have Michelin Cross Climate tyres on the Plus 8 makes it clear how I use the car, as does this photo....

Hood up, heater on and heated seats warming me the Plus 8 is a nice place to be.
On dry roads, hood down, it is even nicer!

The car is all aluminium, the underside is undersealed and the upper surfaces are painted. It is no more likely to suffer from winter use than any other car.
BTW, the car is now washed and looks as it normally does!
