Couple of reasons: - the T6 is smaller than the Sprinter. - OEM. You'd need to go aftermarker for a pop-top. And as as awesome as it is to DIY, not everyone has the time/skills for a conversion. - Volkswagen cult appeal. You can't deny there's a demand for older T2/T3s and Westies. They released the Beetle for nostalgia, they can do the same for the T6.
