What is it exactly? The GLS Grand Edition comes with new interior and exterior elements that make the SUV more luxurious and exclusive than ever before. Inside the cabin are Porcelain/Espresso Brown and designo Nappa leather seats that are adorned with diamond quilting and "Budapest-design piping." Joining the leather seats is open-pore brown ash time and a Nappa leather dashboard. That's enough about the interior though.
