Action always prefers the paper copy of these things... I prefer the digital version.
Here's one on Ebay right now for ~$30 + $5 shipping
That one covers all Ford products from 2001-2003 and has wiring diagrams and service manuals. I've seen many DVDs that cover only certain models (and, it seems, the Town Car is never one of them) while this one covers all models including the Town Car.
I've heard a lot of discussions about which color Ford DVD to buy. Some say there's no difference but my experience is that the red ones cover all models Ford, Lincoln and Mercury (except the heavy trucks).
