Hi Al, welcome to the forum. As you are a big man you might want to add getting in and out of the car with the roof up when you are out testing cars.
Good luck with your search.
I'm 6'02" 15 stone size 12 feet. No problem getting in or out. It's technique, eg bum in first, load left foot then right. Get the steering wheel size that suits your frame.
good luck
Ps I don't drive in wellies !
