Who in the forum can possibly sell their 3.0 TDI GP3 for a maximum of 15,000 euros?

Good morning to all of you, I am interested in a Phaeton GP3. Who of you in the forum sells such a one or has this to do ? Should the V6 TDI be with max. 150t mileage as well as checkbook. For offers or the same I would be very grateful! Lg
