Welcome,
My parents live in Dinedor, just outside of Hereford and i am back there most weekends for the next month. Happy to meet up and chat about zeds if you want to.
I would let you sit in the zed but its a 370 not a 350 so may not be much use. Used to have a 350 though and loved it.
I am 6f7 and must admit its a bit of a squeeze in the zeds (hence why i went for the roadsters lol) but they are incredibly comfy cars (drove from Knockhill to worcester in one stint) and you shouldn't have any problems.
If you wanted to meet up and chat send me a pm
