The stuff you've mentioned is exactly the kind of thing I would expect to be easier to "drag" out of an estate, rather than having to lift over a lip, but I guess down to personal preference.
Yup, the Enyaq is definitely a good option, but again, it's not been available in that price range for long at all
Just checked and I think it has a lip on the boot. Then I see some images where it looks totally flat. Maybe a kind Enyaq owner will confirm
