I have the Haynes Manual and IMO it is JUNK.

My Uncle who is a Mechanic said that in these books they tell you just enough to do basic stuff and so as not to take away the $$ from the professionals they only give up a little.

I think the Helms is a bit more Pricey and may cover twice as much as the Haynes or Chilton's
But IMO if you can afford it or have access to someone with it go with the Mitchell Repair Service Manuals.
