Oldest is a 99 Nissan Altima GXE with 102,000 on it.
Any decently made modern car will last a looooooong time if you even take care of it a little. ALL mechanical objects need routine maintenance to keep running, so ALL cars need to have certain things replaced from time to time, but a decently cared for car should give the average person at least 150,000 to 200,000 miles.
Most Americans just get tired of their cars and want a new toy long before the vehicle actually needs to be replaced and/or ignore the fact that a one-time $1,000 outlay for repair is cheaper than a new $300 per month car payment for the next five years...
