In the market for an FF as a dedicated GT and winter sportscar. How do these hold up over long harsh winters with road salt/brine? I was originally looking at Porsche's for the same role, I know they use galvanized steel frame and cosmoline on sensitive undercarriage parts, provide a 12 year rust warranty. Curious if anyone has any info if the FF undergoes anything similar to protect against corrosion? My daily is a 08' Ram which I get underspray every year to keep the rust at bay. 12 winters and still no issues, same of which can't be said for most Ram's of that era I see on the road around here. Thoughts on underspray?
