I purchased my 04 in Novemeber, and i paid $600 for an option that basically sprays the outside and interior with a scotchguard type solution that protects your paint, seats, and underbody. I have a claim in right now to have a few stains removed, and if they can not be removed, they replace the fabric. here's the website if anyone is interested.

Some dealers and some furnature makers offer this. The "paint" protector is just a wax. The cloth is a true coating that lasts for a few years. They expect you to turn your vehicle over after 3 years average, so they base the cost on this and the life of the product, etc. Bean counters. When its all said and done, I bought leather instead. Much more tear and stain resistent to begin with and I like the feel. ;)
