Polo GTI 1.8 or Kia C’eed GT or … ?

Hi, I’m looking for a sporty car, which can still be moved pleasantly in everyday life. My budget is about 15k€ and I drive about 18m a year with a lot of highway. After some searches at Mobile.de I ended up with the two above mentioned candidates via the 1 BMW, MK7 Fiesta ST and Leon. Before I start my first test drives with the two starts I would like to ask you your experiences and thoughts. From my point of view are the respective advantages/disadvantages: Kia C’ee d GT Track: + Better motorway suitability (golf class) + Depending on the year of construction, there is still a residual guarantee + Better standard equipment (lenkradheizung, Rückfahrkamer, Android Auto) Polo GTI (6C): + Better sports options (Adaptive chassis, Diff standard) + DSG + Better workmanship + Cheaper maintenance (does it agree that the polo does better in insurance and in value maintenance?) + Very advanced engine with slightly more engine capacity (screws that know the 1.8T are always found) That means right now I tend more to the Polo GTI. Would you like to hear your thoughts about this and be open to further suggestions. Is it true that the Polo is cheaper in maintenance/loss of value? How do you rate the two compared to long-distance comfort? How do I recognize with the Polo, whether it has configured Android car? Can you see this already on the picture of the radio?
