It depends which one feels most right for you when driving, parking, getting in and out, etc. If I was spending my own money then it would be the Kia 100%.
I would give serious consideration to seeing if you couldn’t find someone willing to hire/loan you the cars for a day – so that you can make an informed choice based on driving the cars.
The last two vehicles I purchased: one I drove regularly as a hire car (as part of my employment), the other I hired on a 3 week fly-drive holiday to the USA.
value for money doesnt count in motability really, neither does warrantee as the servicing is covered already. What would be most appropriate is to see what is more comfy and easy to drive
