I've done some searching on Yahoo and Google looking for a repair manual for the 05-06 Mustang and have found nothing. Does anyone know if there is one or where to find it?

 

I bought a DVD version off of Ebay. I'm sure you'll find more if you search there.

 

You can get shop manuals from Helm:
2006 Mustang Shop Manual

They're expensive, but I bought one for my Marauder and it's paid for itself many times. If you plan to work on your own car I'd recommend it. When I get my Mustang I'll definitely be buying the shop manual for it.

 

You can also get the Full Shop manual on a CD with a display/sorting program for around $250 directly from your Ford Dealership.
