I bought the manual to help me with a a fuel and starter motor problem on my spider, at best confusing and at worse just downright wrong. The fuel system diagram I've since discovered is an amalgamation of all the fuel deliver systems from al years (confusing as the diagram in the book has 3 fuel pumps for one car apparently) . Similarly the diagram for the starter is wrong showing only 2 bolts not three. Quality of the other illustrations leaves a lot to be deride as well, steer well clear there is better information available online for free.
