The comfort, visibility and storage are all lacking. That said, it's a sports car! I expected what I got and I love it. I have had mine a month and I still love it. It is very difficult to get in and out of. You need to be in good shape. It goes like a rocket, it is probably the hottest car I have owned.
Styling, acceleration. I like the ease of putting the top down. I like the looks of the car top up or down, but the visibility is bad with the top up . Rear visibility isn't too good top down either.
Better upholstery. I am replacing the top at 4 years, 41,000 miles. I will probably have the cloth seats reupholstered in leather, something I wouldn't do if the cloth seats weren't worn and faded. The wheels accumulate a lot of brake dust. The car still looks clean, but i have to wash the wheels.
