I agree. The problem is that people continue to fix things along the way, so it never actually "dies", just constantly fixed. Def depends on what you consider to be catastrphic failure, e.g. death.
I had an XJ I drove for, hm, about 8 years. Only reason I got rid of it was b/c somebody crush a car parked next to it, crushing the side and into anotehr car - bosy was shot. Perfectly driveable. I wanted to keep it but the body work made it impractical.
With old, vehicles, there are 2 routes to go. 1 - fix things, everything, as they break. Car never dies. 2 - fix nothing, literally drive it into the ground, save $$ on no repairs. Anything in between is a waste of $$ IMO.
I did have a '95 which the wheel hub bolts came off of while driving once, 1 bolt shy of quite literally driving the wheel off. does that count? It fit in Cat 2 above.
