US Full Size Wagon as partially daily

Servus! I had already asked here somewhere but received no answer, therefore again. I sold my 335d because of a longer stay in France and bought me a Fiesta ST. Now, surprisingly, this car proved to be absolutely awesome for my German working day (I live in the country, as a 2x15km highway a day) and now I really like the little one. Actually, after returning to Germany the Fiesta was by a g To replace Jaguar (XF/XJ) But now I have considered whether a large, cheaper station wagon might not make sense as a third car (fun)? My need: Lots of space, best 6-8 seaters. Comfortable on the long distance. Cheap fixed costs, consumption is rather secondary. Quite reliable. Should a trailer of about 2to with e.g. the Caterham be able to pull on it (I have the matching tickets). Not needed daily, but only for larger purchases or tours on Long distance. Preferred eight-cylinder, injector. I thought of a 90’s Roadmaster, Caprice, etc. Likes LT 1 What about the idea? What would a good vehicle (keim rust, interior complete, electrical works, drive train solid and tight, scratches and bumps don’t matter to me) cost? I assume to find usable in the range up to 10,000 €, for 17000 I would already find a Superb 3.6 V6? I am grateful for every input.
