I have never bought a service manual which is as competely readable as this althogh it was a scanned pdf. Thank you for this succesful manual also cheaper than other sites.
Thanks for a very good and readable servicemanual. Just what I needed as a "dinosaur technician". I really recommmend this site and will come back.
