(Re-) Beginner – Buy ZR7S, is offer ok and pay attention to what?

Hello. After 10 years no motorcycle anymore I play with the idea to get back on the two-wheeler. I looked on the market without any obligation what there is. I immediately noticed a machine: Kawa ZR7S, 03/2001, Blaumet., approx. 12,000km, 2. Hd, so far very well maintained and no maintenance stump. Stands at the dealer and should cost 2.500.-€ (incl. new TÜV and inspection). Actually I wanted to spend for the re-entry max. 2.000.-€. If I compare something d Is there something special about the model that should be taken into account?
