Thanks for the response. I tested the boot and the wheelchair slid in easily. It would have been better as a hatchback. The i4 is a hatchback and it was easier to put the wheelchair in the boot. The Ioniq was big enough.
I live in Birmingham. It’s over 2 hours away from Colne. I don’t think it would be feasible to speak to them.
I’ll sleep on it and see if I settle for one or the other.
