i dont find it any harder to put things in the trunk. though i never put anything in there. i think it looks good on an elise and follows the lines of the car.One more thing considering the size does it make it an issue of putting stuff into the trunk.
It was on my car when I bought it and I hate it. I looked into taking it off but contrary to what others have said here on the forum, removing it will require repainting the rear of the car. Blocks about 1/3rd of the rear visibility.
