I used to work for a dealer back in the late 80s and early 90s. We used take bikes for a gentle run after PDI to make sure that everything is ok. Then recheck levels etc. 7 miles sounds about normal. I wouldn’t worry. Its a sign that the job has been done properly.
Looks like my Stelvio only got pushed into and out of the box. Then the workshop and showroom before I picked it up. Only 1 mile on clock.
