I'm dating my Dodge here, but I think I paid $40 for mine. Some of the diagrams in it will take you several hours to figure out, but at least they're all there! Best money I every spent.
You know, it wouldn't cost the auto companies more than $10 to put the entire service manual on a CD-ROM. They could even put a standard USB or RS-232 diagnostic connector in the engine compartment that you could connect to your PC to trouble-shoot everything yourself. Naturally, as long as their dealers charge $70 per hour for service, that ain't gonna happen, though...
