This weekend I saw a high school classmate of mine who has a 280Z that he has owned for 20 years and 5 of his 7 children have used as a daily driver. He told me the car has 650,000 miles on it with only one valve job in its history. Simply amazing! Can anyone top that?

We have estimated based on the limited info that I have from previous owners plus the miles I have put on it, that my 64 L320 has between 800k and 1,000,000 miles. I'm on the second engine since I've had it not counting the original engine that was in it when I bought it 25 years ago.

My father has a Kentworth t600 with 1.8 million miles on the original motor.
