I found it well fitted, but not sloppy. Very good elastic at the bottom of both front and rear. Underbody fasteners are vinyl covered for non-scratch. The material is like "Silver- Hypolon"
I also imagine that with the 451 lead in UK that they probably have a custom 451 already in production.
I suggest asking if they have sent 451 inventory to Texas yet.
I liked the way the cover locks onto the side mirrors and holds the cover on the car while in the process of folding and unfolding the cover. Otherwise it would want to slide off the car.
The carry case is not an afterthought, quality material and a long zipper. Flat, square, fits in the trunk (trunk?) well.
I forgot to mention that the price (incl. shipping) is lower than Covercraft. Delivery was about 8 days
