Gentlemen, is there anyone in the US that makes the fiberglass tonneau for the 2000XK8 convertible?

 

Mina Gallery makes one.

I think the adamesh one is nicer as you don't lose the use of the back seats.

Please note that I have heard all of these rub and can cause some paint wear at the car's point of contact. However, I have never used one or seen one so I cannot speak first hand,

Best!

Personally, I like the leather tonneau..
I'd be concerned about the fiberglass rubbing and the paint.. Also, there are times you may want quick removal.
