Nice work Gav, only had a quick read cause I'm at work atm. You might have covered it in the content, but maybe a quick reference list for some of the good things to look for in the cars would also be useful? Things like round top su's, electric dizzy, rear discs, uncracked dash etc. I was just thinking some of the more common mods people do to the cars or hard to find/repalce bits. Although I suppose some "good" things are a bit subjective depending on what you are doing with the car.
Anyway, just an idea
