Very nice, but there are no leather seat trims available (maybe they're not available from launch?), not all of the other options are included and there's no obvious way of selecting the 'Lounge' or 'Sport' trim level apart from choosing the upholstery type.
The configurator has a few minor bugs as well, including indistinct 'Save' and 'Cancel' buttons for one option in the English language version which are very hard to select. (The Italian version of the configurator doesn't appear to have this problem.)
