Mechanic's/shop manual ?
 

Folks,

Anybody know where I can get an (affordable) mechanic's manual (NOT the owner manual) ? Need to pull some panels out of my interior. Would like to have detailed instructions in order not to damage anything.
Had a shop manual for my Viper and absolutely loved it. A friend told me that the Porsche shop manual costs about 700$ if bought through the dealership. Anybody know of a cheaper alternative ?

Thanks !
