When I did a test drive last winter, I felt that the ISOFIX was hidden very far under the seat, difficult to reach. 1. Has this been changed with the back seat upgrade this summer? I really need to know. If it is easier, we're really considering to replace our order to get the new back seats. 2. Is it easier to access ISOFIX with the included seats than the leather seats? Thank you so much for quick answers!
