the kona isnt what i would call huge.
small suv types available in auto are:
mokka i found it a bit short of head room
arona my thought was a bit cramped.
kona bit awkward getting in and out but that was old model
juke hybrid perfect in everyway (well almost) took delivery 30 may 4 month wait
t-cross again bit tight getting in/out
yaris cross looks great havent tried as it wasnt on scheme when i was looking
s-cross not tried
i30 very good but a bit low for me
cx30 not tried
all similarish i went for the juke hybrid for price and getting in and out.its shape suited my disabilities perfectly and the fuel economy is excellent 58+ has dropped a bit in the baltic weather but still much better than i got in the countryman.
unfortunateley stock will be low and any factory order will be months rather than weeks.
best bet make a short list and test drive them all be sure which ones will work for you then start ringing dealers to find stock, be flexible on colour and you may get lucky. you may have to travel to get a stock vehicle and dont forget you will need to go and sign to order and again to pick up, but then you are free to use your local dealer for servicing etc.
