You know those little packs of "dessicant" you find inside a box of new electronic gear like cameras, dvd players, computer accessories, etc?
You can purchase a large one designed for cargo containers & keep it in your interior when you're not driving the car. It will suck the moisture from the air inside the passenger compartment.
McMaster - Carr Supply Company part number 2228K6 (about $13) will get you four such bags. 32 of them are enough for a 20 foot cargo container. I'll bet one can handle a Pantera interior.
