Yeah salt is bad but I've driven my car through every winter for a decade. No rust or paint damage.
Well my exhaust looked like crap when it came off for the upgraded exhaust but who cares. My cats were shot before the 80K mile mark but I don't think that in particular was because of salt.
My rotors looked pretty good when they came off after a decade of winter driving.
These modern cars aren't like the 1970's Porsches. They're not going to cave in on themselves because of salt, more so because of cheap, mass market oil.
That doesn't mean you should wash off all the salt though, I'm just saying it's not like kryptonite if it gets on the car.
