Let's say you could figure out a way to make and sell copies of this tail for $500 apiece. With U.S. gas prices at $3.61, the payback of going from 99 to 109 mpg (US) is a mere...

155,698 miles / 250,571 km

Of course if you halve the cost, or double fuel prices, you halve the payback period/distance.

Food for thought anyway, if financial issues are your main motivation for modding.
