Well its finally out and I got it.

Its very nice and compliments a w124 owner.

This is the only book i've come across that talks about all the w124 models such as the diesel engines and the v-8 versions

First it starts off with the history, various components...the last section deals with mods u can do like changing the headlights, suspension components and such.

Oh the other cool thing is a great troubleshoot guide....it says which models usually have the problem and what is causing it. It actually talks about the head gasket problem with the M104 engine!
