As has been said, it depends to a great degree on the make of the vehicle, then the model. But even uaw vehicles are getting better about longevity. Maintenance is critical no matter the vehicle, but some vehicles, with proper maintenance, the sky`s the limit on how long it will last. My 2009 Toyota Tacoma has 101,900K on it, and I really feel that it`s just now getting settled in well. Certainly, there will be the usual maintenance issues, normal wear and tear, but I really expect no major repair issues, and as of right now, expect this is the last vehicle I`ll ever buy for myself. If it doesn`t last for at least 500,000, I`ll be very let down.
