Solid, economical used car up to 10,000 euros

After having driven an old 96 Astra for 5 years, which cost me a lot of money (repairs), sweat, nerves and above all gasoline, I am now looking for a new vehicle. The important things are: – economical consumption !!! – solide (I don’t want to go to the workshop every 4 months) – year of construction not older than 2005 – petroler – cheap in tax/maintenance – preferably German factory (because I think as a layman, the h I mostly drive the highway (working trip, daily about 80 kilometers.) Also downtown trips. The performance should be balanced. I am not a racer and do not need a thick machine and cool sound but also a mini car that does not come out of the kink. So no 2.0 but also no 1.3 machine. Very important to me is above all a low fuel consumption. My Astra now has a consumption of about 10 liters and that is just too much for me. I, due to the age of this vehicle, constantly had to do any repairs. It would be nice if the new car were less vulnerable. Buget is 10,000 euros (11,000 euros under certain circumstances). Without funding. I thank you very much in advance for all your tips! Since the current Astra is my first car and I had soooo damn stress with this car (in terms of repairs, fuel costs, etc), I just want to do much better this time Therefore also this thread.
