The mailing, by DM agency Draft London, is one of the company's most expensive packs to date.
The mailpack comprises a boxed hardback book and comes with enough bookmarks to put one in every double-page spread featuring a different car.
It aims to reinforce the fact that the car has developed over the years and features the new convertible and the recently revised 9-5 car.
Elliot Grace, marketing communications manager at Saab, said: "The mailer is designed to express the premium qualities of Saab - standing out but without it being brash."
Arthur Parshotam, creative director of Draft London, added: "When it comes to repurchase, customers are being seduced by the likes of BMW or Mercedes. Our message is that their decision to buy a Saab was a wise one, and we wanted a mailer that would knock people out creatively."
On top of the initial run of 10,000, Saab will automatically send the book to customers who reach their repurchase window over the next year. It plans to use the pack as a major plank for building customer loyalty.
