Saab 9-3 cabrio Aero buy ?? And antenna problem?

Hello Your Saab driver Are you going to buy a Saab 9-3 convertible, 2002er driven by the doctor, 56tkm checkbook, Aero with 205 hp (or 209???), unfortunately manual transmission… grey metallic, condition ok., leather black with electric seats. I actually think that I don’t want to pay more than 10t€ for it, what do you mean ?? realistic or not ? stands at the VW dealer for 11900 euros. Are there special weaknesses to be considered? Why does the car have 2 antennas ? right and a big electric left ? ? And how can you disconnect the big ugly antenna or switch it off ? Listen to CD radio anyway. Does the car have timing belts or control chain ??If first: change interval ?? Thank you! MFG Markus
