Haynes used to nick the exploded diagrams from the factory workshop manuals- maybe its a copyright thing, but they have certainly dumbed down a lot these days, and the printing and photos are definately lower quality.A lot of the procedures they used to include they now don't, considering them to be to difficult-some of their 4 or 5 spanner procedures are relatively easy- I think they have fallen foul of nanny syndrome and think that if someones corpse is found with a set of spring compressors and an open manual then they'll get sued........I think a campaign should be started for the "Return of the Exploded Diagram".
I have two 205 manuals, a new one that I bought, and an old one that the bloke I bought the car off fetched round a couple of days later -the earlier one is about twice as thick as the newer one.....
Any spares shop should have plus-gas in stock!!!
