I have a 2k max gxe 5spd and has 43k miles on it...when the factory warranty says "corrosion warranty for 60 months" does it include some rusting inside the engine bay? the frist owner of the car was from new york so its been driven on snow and had seen some salt..so there are some small rusting inside the engine bay...i wanted to ask you guys if its worth it to take it to the dealership or is there quick fix to do it myself? thanks in advance.
