Hate the constantly sliding images. Porsche would have been wiser to anchor on the left, Exterior and Interior views, one on top of the other, to display the configuration the user selects. The right side should be a simple scroll with smaller thumbnails of each option for the user to select. Let the user expand those thumbnails or detailed info bubbles on demand for the options he wants to see. It's infuriating to have to wade through pictures of every single option you don't need to see that fly over, left, or under the config pictures.
Whomever Porsche hired to build this new configurator must specialize in developing for miniature mobile screens, so much so that they force unnecessary layering for desktop websites too. Not impressed.
Another thing that would be nice is if Porsche offered a view that simplified the comparison between vehicle trim levels. You would think that the Comparison page would do that cleanly. Nope. No one-page display of what options are available, included, or exclusive with each trim level. The experts know. The prospective new buyer to Porsche wouldn't have a clue.
