Purchase advice: Seat Leon Kombi from 2016?

Hello all, my current car (Ford Focus, 2002 BJ, 202000 km) is unfortunately becoming more and more uneconomic, so I think about buying a new car. Since Leon like me is a rather nice little station wagon, I thought about it. I drive about 30000 km a year, friends and hobby due to a lot of highway. What I want is a gasoline that I can drive for a long time. Tempomat is important to me and it should also be able to drive faster (around the 220 would be great). My budget is c a. 18.000 euros. Now I have looked at mobile and saw that unfortunately there are not many Leons up to the budget. I also heard of a steering chain problem that often led to the problem with relatively young engines, however, this should extend to the whole VW family. Does anyone know from which model, respectively BJ, this is no longer available? Is the car useful for the purpose, or did I now let myself be misled by the Internet and friends? D Anke! VIele Greesse
