Recommended purchase: Seat Arona or Hyundai i30

Hello together, after our main vehicle (Jaguar XE) currently has bigger engine problems, we are looking for a “cost-effective” and reliable second car. It is important to us that it is a reliable vehicle in the long term, with few weaknesses known, few repairs occur and if something should be manageable, the repair costs are manageable. The same applies to the maintenance. It should become a fuel efficient petrol, either compact class or Klei n-SUV/Crossover. The Seat Arona has been selected for more details or a Hyundai i30. The budget is 16.500 € – equipment doesn’t matter. Car is mainly moved in the small town/overland and every 5-6 weeks by 300 km on the highway. What experiences do you have about the two vehicles/engines? Thank you for your input!! Patrick
