No, they still do.  :lol:

Plus, maybe evey Dub that comes along for sale, twon't be need'n thm gosh darn fler pans

They don't rust out from salt on the roads, but they still rust out down here.  Usually from the inside out.  But, it's no big deal.  A correctly cut piece of plywood will keep the battery in the car and a good set of rubber mats will keep rainwater from spraying up through the floor on you.  Floor pans are over-rated!
