What do you use for your Saph Cossies?
Was looking at the Haynes manual but it doesn't cover the Cosworth. Is it worth buying the normal saphire book for the interior and other general bits(they are all sealed so I couldn't have a look inside).
Secondly, I see a lot of workshop manuals for sale on disc from E-bay. Anyone bought one, any good?

Any advice much appreciated.
