I am a similar height of around 5ft 6inches and I have no problem ?.
Granted, I don’t sit right on top of the steering wheel, but I don’t sit in the back either, if you know what I mean.
To be honest, I adjusted the seat on the day we collected our ZS EV and I think I slightly adjusted it once a couple of days latter.
It has know been in the same position for almost 18 months and 13,000 miles.
The same applies to the steering wheel adjustment, set it once, that’s it !.
I find the seating position very comfortable.
I hate it when in some cars, you seem to always fiddling with the adjustment in an attempt to find a good position.
In this respect, I find the ZS EV very easy to get on with.
My brother has a ZS EV and a replacement knee and hip to go with it, he agrees that the seating is very comfortable !.
