The classic Ioniq had a much more useable trunk/boot than the old Kona. I know that the new Kona has improved on that, but I don't know by how much. Have you ever transported a bike in your Ioniq? If so, take it with you and see if it will fit in the Kona, otherwise you may end up quite disappointed should you ever need to transport it again.

 

Thanks @KevinT for your insight. I haven't carried a bike but golf clubs and to do that I need to put down the back chair. Guess not much difference with Kona. But I do have difficulties seeing how a Crossover can be more fuel efficient than my sleek aerodynamic Ioniq without mentionning wind noise but guess I'll need to take it on a trial ride and check it out.

So the dealer wanted to offer me a buyback for 2/3 of the original car price after 3 years. However the only model that I would consider would be the Kona N-Line (doesn't have those multi color wheel guards that I find really ugly). However that would mean I would need to cough up the same amount of cash on top of the buy back amount I would receive for a car that offers nothing better than my Ioniq so no... turned down the offer.
