You can buy aftermarket kits that provide a butt and lower back heat pad that slide between the leather and the foam cushion. They cost about $200/piece + install. As for the ATX issue I didn't notice that requirement till just now. Yeah a west coast car is always real nice when looking at used. Even though I shod it with winter rubber my SVT generally only ventures out on the real nice dry winter days. For the nasty stuff we use the Dakota. If you think that price is good you should see what a dealer we give you for trade in. Yikes!
