When was my car made

is it possible to tell what day and month my car was made from this vin no. 138570b120568?it was 120568th made and it was built at the baltimore gm plant

No. The vin number can identify the model, but not when it was manufactured.

Look on the drivers side door jam it will give you make, model, yr., color code, air pressure for tires and more... if the vehicle was made in the 6th month this will be the following yr. car.
