mojomoh When I said bigger I should have said bigger floor area. My mobility scooter would easily go into the Octavia in a front to back arrangement and also side to side, but it only fits side to side in the Kia. There was a time when many dealers must have thought me mad I would go into a showroom with a tape measure and measure everything that appeared suitable, there were not that many. Things like Mazda 6 hatch or estate but hatch has loading lip, Ford mondeos same again, and some others.
If snow had not fallen on the day I was due to test drive the Mazda 6 estate that's what I might havepurchased. My Kia dealer only had a Pro-Cee,d in the showroom but the dealer rep assured me it was the same boot as the Cee,d so I measured and it would fit. The SW also lets me get some luggage or a large dog in as well, and most of them can jump in by themselves a big help as I cannot lift them. Even then the flat floor lets you get the dogs front legs on the floor and they help you a lot when you lift in the back legs.
In case you wonder I do voluntary driving for an organisation that uses large dogs and sometimes use my own car.
