I am getting a car with the hardtop. So we thought it would be a good idea to get the Lotus hardtop storage bag offered in the accessory catalog. We ordered it without getting a firm price thinking it would be a couple hundred dollars. It came in, it was $317, plus tax at my dealer. The bag is a canvas/ballistic nylon flat bag that is padded on both sides and lined with a soft knapped material on the inside. It has a storage pocket for the piece of trim that apparently has to be (removed/installed?) when putting on the hardtop. It closes with straps that have snaplocks (I don't know what they are called). It has two straps with D-rings that are used to hang on the hooks that are included, to be installed in the wall.
It has "Hardtop Storage System" silkscreen on the bag. It also says Lotus,, but no logo. It is black. I would say, it is a bit expensive for what it is. I would suggest look at the bag that comes standard with the hardtop, before purchasing. Maybe I will be happier with my purchase when I see the included bag, or when I actually have my car and have something to put in it!
I will try to post pictures tonight, if remember and get a chance.
