New purchase ix20 automatic ?

Hello , my parents are planning a new car purchase.Minimum requirement :Automatic , since they are both meanwhile above 70. An increased sitting position is also a must. Since they came to the Ix20 in the narrow selection.5 years warranty is also a nice gimmick. I was there at the first consideration and think that this vehicle would be for them. But what I noticed is that the vehicle has a not so great efficiency class.Class D is not really great. Now I wanted to ask v on you professionals, as the real consumption of the vehicle is, what’s in it of discounts for day registrations and how generally the vehicle does so. Would be great if you would list the pros and contras. Thank you and greetings, Adrian
