I had been looking for this configuration and color since late last year, before any 2021's had arrived to the US.
Of the ~2,400, 2021 GTI's available in the US (according to cars.com), there are only ~100 that are Autobahn and 6-Speed manual. Only ~10 are DIB. Only 2 were under 500 miles from where I live before I purchased mine.
One reason I bought now was I am not sure about supply for the rest of the year, as the VW Puebla plant stopped making regular Golfs last month, and there is a current chip shortage, slowing down production of at least the Jetta at that VW plant. And with new MK8's scheduled to arrive sometime later this year, didn't know for how long the MK7's would continue to be manufactured.
