Look closely, at the way the speedo numbers line up.

They have the shape of a dome, with the center numbers higher than the side numbers.

One thing is to have the miles (far right) number slightly off, but numbers on the far left should be straight, with the center numbers.

 

This car just sold for over $60k at Barrett-Jackson auction very recently. Also, just look at the pictures. The thing literally looks brand new.

 

That does not look like a tampered odometer by any means.

 

The only number that doesn't line up exactly perfect is the 6, which is the number that is probably setting to move next. It does not look tampered with.
