Funny prices for used Saab!?

Hello, I was in Berlin with BMW on Friday and I had a 5s count and got an offer for my Saab convertible. Is one of the last built from 08/2001, the fully equipped Summer Edition 2.0t (only Navi was not available yet) in black, switch, full leather, brainwashed on 210 hp with sports suspension. Only 54,000 km run. Set of winter tires. Doesn’t look completely licked, but has nothing that goes beyond normal traces of use. As everyone here know, a dream car. t BMW? 7500 Euro. The seller was totally embarrassed by the DEKRA calculation, because according to Schwacke the dealer purchase price is 11.400 Euro and according to ADAC the box should still be worth about 13,000 Euro. If you pull off 2000-3000 because of the general situation, you still end up clearly above it. I know that the dealers currently not exactly after used ones liking, but my question is: Is this already due to the insolvency for Saab? Do you think that the old convertibles on the private market still so are as popular as a few years ago or I prefer to drive my treasure until it breaks apart, because where do you get so much driving fun for so little money?
