yeah when living in cowtown I always thought it was weird when people drove around their luxury vehicles in the winter. they get destroyed there. keep a beater around
Would I drive a 911 or M3 in the winter? Hell no! But a luxury SUV? Absolutely. That's what these things are designed for. As long as you're rinsing off the salt regularly (including the undercarriage) then there's really no issue. Not sure about other euro brands but BMW and VW have a 12 year unlimited mileage corrosion warranty and they don't restrict it according to the region where the car is driven.
