>20 yearsparts starting to go out of stock. Rubber getting tired everywhere. Will probably need to go to scrap yard for things occasionally.
>30 yearsUnless the car has GOATed reliability and super responsible owners in terms of maintenance, the car is gonna have constant big jobs on the horizon, parts will be scarce, parts available won't be OEM, they will be gone from scrap yards, and rust will probably start having to be addressed.
I think 30 years is really the limit. That's when it becomes a project car. Once you get ahead of all the work it needs done, it can be a daily again. But you're stuck with bargain bin aftermarket and used ebay parts for life after that which makes repair intervals even smaller. It basically gets stuck being a shitbox for life at that point.
