hello to all of you…please ask for your help. need a second car for my wife for about 8-10tkm in the year and a saab is definitely in question. what is to be paid attention…has the motorization chain or timing belt described in the case? he is without turbo or? what known weak spots are to be observed and how long will he keep in good care in the past and in the future? from when to when was this variant built? how much can he use 1 or 2 hand with good equipment, service at saab regularly with 100-150tkm running performance? mfg and many thanks to roger
