Mine was a 2018 bought in June 2019 with a bit under 40 miles on it when the test drive started and roughly 80 when I finished my test drive. But I was in love pretty quickly and knew it would soon be mine.My TourX had been at the dealer for around 6 months, and had a total of 16 miles on it when I started the test drive. We also filled the tank before the drive, so it's possible it hadn't been test driven yet. It was up to 27 miles when I signed the paperwork after the test drive.
Not necessarily the case for all TourXs, but they seem to be a car that people specifically seek out, not something the average person test drives because they see it on the lot.
