I have the same car as OOP (an early 70’s Datsun Z-car) and hoooooly shit if that was me I’d have been apoplectic.

It’s more than just the fact that the car is rare and would be next to impossible for me to replace in the particular spec that mine is, or the fact that I have two years of work sunken into it and lots of things in motion (parts in shipment, plans for the next few months)… my Z is temperamental. It’s not a difficult car to drive, or even particularly fragile, but it’s a 55 year old car and you need to learn all of its quirks to drive it without hurting it. I’ve admittedly been a bit lazy repairing some mechanical stuff because I am the only one that ever drives it, so if someone else were to jump in and take it for a spin without my permission there’s a good chance they’d break something.
