You could be right on all counts. But I'm 100% confident I can keep my 80 series running another 50 years with relatively minimal work (occasionally rebuilding things, maybe some rust repair if I get lazy about rust prevention, etc.)--I can at least predict and understand all the problems I'll encounter, and none of them includes trying to reverse engineer a CAN network.

I have very little confidence I'd actually be able to keep a Grenadier on the road forever. I suspect it's at most a 20yr car. We'll see maybe in 30 years I'll get a used one and prove myself wrong.
