I love the idea of the Leatherman with a chassis number engraved. That would be enough for me to finally retire my current one after nearly 20 years of loyal service.
In terms of the handover experience though, I'd actually like to propose a "blended" experience:
1) An online course that covers the fundamental functions of the vehicle with clear learning outcomes -- At the end of this course, users should have a "101" level understanding of how to operate a proper 4x4, how to drive them off road, and how to maintain them in general. Make this something that comes with a credential, like a digital badge or something, and make it so it can actually be useful for non-Ineos owners too (i.e. Land Rover used to publish a fantastic brochure about driving off road that, while specific to selling land rovers, taught me a great deal back in the day about the ins and outs of it). Given this is intended to be an heirloom vehicle, being able to put my son through this course when he's a bit older would be fantastic. And, as part of this, add some "201" level stuff that is specific to the Grenadier. Let me access it the month before I take delivery.
2) When I arrive in-person for pickup, have the grenadier agent take me through my specific vehicle - any options I've ordered in terms of how they work, and reinforce the key parts of the online course.
3) Slightly controversial - but what are the little foibles and annoyances that I should know about that real-world users have discovered? I don't want a ton of focus on this but some honesty/transparency; for instance I discovered myself that the Freedom Top on my old jeep had screws to hold it down with big handles on them; these things were super annoying to use and put in because they are easily cross threaded, but turning them backwards first gives a really solid "Clunk" to know the threads are properly engaged. That's just a little owners' tip that would have been handy to be told by the Dealer.
4) Introduce me to the service manager or, if I'm not local, give me the information of the nearest Bosch service place to my home with the number of the service department, and create some sort of connection/relationship there.
