Family car up to 6,500€ – which one should it become?

After I have already informed myself in some special brand forums I have arrived at a point where I have quite precise ideas about which should become our next car. First of all the boundary conditions: we need a family station wagon, in which I can sit and drive with my 1.90 m front, while behind me at least a 1.60 m large person should have enough legroom to sit comfortably. The car will probably be about 10-1 3,000 km a year, which is why a petrol engine is probably more useful than a diesel engine, especially since in many forums the diesel is warned of at a certain age, as there are large follow-up costs to be expected (DPF, turbocharger etc.) In addition, the car is probably used 50-70% on short distance in the city. The budget for the car is approximately at a maximum of 6500 €. If it is a super offer it can also be quiet 7000 €. First of all, it is planned to drive the car For the next three years he should be as inconspicuous as possible in the maintenance and repair, in order to bring correspondingly low follow-up costs after the purchase. Since my wife is finished in there. three years with the study, there are then other possibilities. at this point again many thanks to the forum users, who have already helped me intensively and expertly with the preselection. But now the ones chosen by me in the inner favorite circle 1.) Skoda Octavia II 1.6 MPI from year 2005 with 102 hp 2.) Toyota Avensis 1.8 Year of manufacture between 2003 & 2009 with 129 hp 3.) Mazda 5 2.0 from 2005 with 146 hp (6 gear) 4.) Mazda 6 1.8 from 2002 & 20 08 with 120 HP 5.) VW Passat 1.6 MPI from 2003 with 102 HP Already before thank you for your opinions and information. This forum has helped me so much.
