I want to get a repair/shop manual for my new-to-me 89 LX 5.0 Vert. In the past I have usually bought the Haynes manuals for my older cars. For the Mustang, which would be best for general reference? Haynes, Chilton, the red "OEM Ford " manual? They seem to be $20-40 for the Haynes or Chilton and $60-100 for the "OEM" (I put that in quotes because I don't know if they are actually Ford publications). Or something else?

Which is the most complete, accurate and useful? Thanks.
