Purchase aid

Hello, I’m actually from the Opel Dickschiffliga, but I have to change to something else because of too many construction sites and that’s when the Grand Espace came into my eye. So my frankophile side of the car was awakened again. I had a CX at the beginning of the 90s 2x Citroen BX 14 and 19 and for a very long time. (dream car) Now to my question, there must be a diesel with automatic, (rigid right leg ) I need a lot of space and a trailer, he must be able to pull. The 3.0 is not good I was warned and the consumption would be very high, it would probably be an engine bought by Hyundai. What does the concentrated forum power mean which should I take, how are the average consumptions, how much tax gets “Willy wurger from the tax office” what is it about the reliability ? I am an old car.ler, but screw, is not so popular with me anymore. Questions about questions, i ho ffe you can help me
