Half dozen years ago I got them for my Ranchero. Nice vinyl or plastic coating you may write on then erase, easy to read an understand. Thinking they were 20 bucks or so, well worth it in my book! You can get diagrams an blow up, laminate yourself, wasn't worth my time for what he charged! I did deal with him direct an he does some dealing!!! Can't remember what the deal was,,, something 2 for 1 or other car half price,,
I ordered one of the 11*17 for my Comet. It's worth the money ($15.00) to me. It is enclosed in plastic so no worries abt getting it soiled. It helped me to find wiring right away w/o a lot of tracing and solve my wiring issues a lot faster. So what is time worth to you? Is it real schematic w/ wire gauge sizes, fuse capacities, voltage readings, etc.---(No) At least the 11*17" is not; I don't know abt the poster size. It's fairly easy to read, the colors make it easy to follow the circuits. Wud I buy it again---YES.
