I came across a price list from SAAB in an old manual that someone has just given me. Thought it might be of interest - seems I can't attach a photo or scan of this so have written it out below - if one of the mods can help I can easily send a copy via e-mail for you to post. Apologies if the text is out of line - I cant seem to get it to post in the same layout as it is when I am composing.
SAAB Recommended Price List Ex. Works Issued by SAAB GB Ltd, Slough, effective from 1st April 1973
That's a great find! I have the original receipt for my 96 from Haymills (also in Slough) in Feb 1972. I'll try and dig it out and see how prices compare! Cheers
