9-5 Aero – Control before purchase ?!

Hello dear Saab municipality, after 4 diesel years (2years 9-3 2.2TiD, 2years 9-5 3.0 TiD) I now have the opportunity to get involved with an Aero sports combi. A test drive (with another Aero) has already been completed, the impressive driving performances generate a very big “have-will” – moment The Aero is 2 months old, has 17000km (!) on the speedometer – was moved by a regional manager Saab Germany. (The man must have lived in the car…) h as Auto-Technik-Laien a way to determine whether the predecessor “reasonably” drove or whether it is rather heated? I can’t recognize it on the tires – the used winter tires are already dismantled Many greetings from near Nuremberg Maik
