Genuine Subaru factory service / workshop manual ( hard to come by ).
I have found this invaluable during my ownership of a 1993 Subaru Sumo for the last 8 years.
It covers both the 1 litre and 1.2 litre 2wd and 4wd European / left hand drive and right hand drive. Also for GCC countries.
It is a very comprehensive manual and is in good overall condition with very light marks and wear mainly to the cover.
It is in English language only.
Thanks for looking.
