Kia Ceed SW or Hyundai i30 Kombi as a family?

We want to buy a combi as a family with 2 children. We drive about 10-15,000km per year, 90% motorway. After a long research we now have the following selection: A) KIA Ceed SW as “Edition 30/Nightline” (EU import from CZ) on 17-inch rims, 140 hp 1.5 T-GDI equipment different from Hyundai: metallic paint 7 years / 150,000 KM warranty B) Hyundai i30 Combi as N-Line (German dealer, day registration) on 18-inch rims, 140 hp 1.5 T-GDI MILD hybrid equipment, different from K IA: dead angle warning, cross traffic warning, emergency call function, electrically adjustable seats, digital cockpit, uni-painting, alarm system 5 years / unlimited KM warranty Both cars are quite comprehensively equipped (full LED, parking aid front/back, camera, Navi, seat heating, electric mirror, emergency brake assistant, Lane-Assist, etc.) and are new at about 23,000 Eur incl. transfer. Finally they come from the same group and have the same base. It is also an EU import (which doesn’t matter for the warranty). I think the KIA is slightly more optical and it has 2 years longer warranty and no (possibly vulnerable) MILD hybrid. At Hyundai I heard about a “harder chassis” and also the trunk is a little smaller/bevelled and the interior seemed a little higher at the KIA. Also because of the 18-inch rims I have worries, because we especially have high comfort on the back of the car. f Langstrecken is important. What would you decide to do? Or would you take it all over again? Skoda and Co actually fall out, because (with similar equipment) significantly more expensive and budget is at max. 25,000 Eur.
