I wrote an email to the German Ford Event team and requested some more details, also if they offer reservable slots for test drives. I would also have to travel, that‘s why I want to know in prior what Ford is offering on-site. I will let the community know once more details come available.
I just got an answer by the German Ford event team. First off all, they apologized for the late response. The email Account was opened this morning and therefore the answer is delayed. However, they do not allow to drive the Mach E onsite, but you can pre-book to ride it together with a Ford official half-hourly.
All German reservation holders should have the original invitation eMail. Use the EMail provided to pre-book your ride. Enjoy, I will be there and reporting
