I’m 6’5″ and 18st, had no problems with,
Ford Kuga
Seat Ateca
Older Honda CRV (2008) – not tried the newer ones
My current Enyaq is the 85x SportLine Plus, the seats are ok but the seat base is a bit narrow, the side bolsters (look like wings) can stick into me at times. My son is 6’3″ish about 19-20st and finds it difficult getting his head under the windscreen (sloping part of the door opening) getting in, even with the seat fully back.
As has been said above, take a day to go round dealers and have a sit in as many as you can, you’ll get a few surprises!. I tried the Toyota BZX4 which is taller than the Enyaq and couldn’t even get under the roof to get in!, Nissan Arriya (even taller) even with the seat lowered right down had my head hitting the roof lining and the steering wheel hitting my legs!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
