Re: the length of my cardboard boat tail:

The tail as you see it only adds roughly 4.5 feet to the overall length of the car, beyond the OEM bumper, including the tail lights glommed on the tail's transom.

The 62.5 in. measurement you see in the diagram was just there to provide a reference to another Metro owner who inquired - it shows the length from the forward edge of the rear taillight assembly to the tip of the tail.

There's still a fair amount of "car" underneath the forward end of my boat tail as it appears in profile.
