We have a 2015 Pure that we are pleased with. So much so that we're shopping for a 2015 to 2018 Cabrio. How does that tailgate open without the glass panel above it, which of course opens first and in turn releases the lower gate on the standard Pure.
Here is what a full Cabriolet looks like.Thanks for the answers! Got it.
