Cars don't have expiration dates.
Say it, then repeat it.
If you maintain it properly, drive it properly, etc, it can reach well over 500,000 miles.
Some cars have even hit the 1 million mile mark.
It's just a machine. It doesn't maintain itself, repair itself, or do anything else on it's own, except alert the owner to when it needs those things.
So, reliability is on you. Longevity, is on you. Maintenance, depends on how you drive it.
It's like asking how many years a person has left, if you think about it. Might die tomorrow, for no reason. Might live to 104. Depends on lifestyle, diet, conditions, etc. There's no specific "expiration date".
