Saab 900GL Bj 84

Hello. I’m new here in the forum. I’ve been looking for a long time but unfortunately I didn’t find anything on my topic. I might have a view of a Saab 900 GL with Bj 84. Since my father has already driven Saab I would like that in principle. Now I wanted to know if you can help me with technical data about the vehicle. Motorization? Consumption? Vulnerabilities? Here was the information. The vehicle was in 1st possession until 1999 and was maintained until then every year. into the hands of a Swedish car fan, who cared but very little about it. Since 1999 not much more than 1000 km a year. What do you think of the offer. Thank you already in advance for your help. Martin
