Multi-driver seeks vehicle

I’m looking for a new car, whether used or a new car is still standing. If so, which one should be? I have no idea to be honest. The budget is ~20.000 + – of course. Should it become a diesel or rather not? According to my information, a diesel would be worthwhile for the work path alone (~95% motorway)? I’m a relatively sporty driver. twas, which is motorized accordingly, but no racing emblem! I am looking for a mixture of equipment, comfort and speed – the consumption is also a bit interesting. Of course, a 7 GTD with the 184ps machine is directly in the eye. Are there any opinions? Alternatively, the Hyundai i30 N performance would be quite nice, but is a petrol engine and it will certainly treat itself to the one or other liter. In addition, I did not have any of the Hyundai so far from my acquaintance. I don’t limit myself to VW or BMW. What I’m offered the best is bought. It shouldn’t be a limousine if possible. 4-door (á la GTD) is fine. But doesn’t have to be an A6, so no “family coach”, understand? What would be interesting? And above all: Does leasing or used car leasing pay off? Bottom line: – A mixture of sportiness, comfort, equipment – Ke in family car – Diesel (?) – Budget 20,000€ + – 5000 – No 150,000km – ~42km Easy work path This one would be interesting: Mobile opinions? Greetings!
