It is all a matter of perspective...
When I started driving my Z/28 30 years ago, it got 8 miles to the gallon as long as I kept my foot out of it...Full throttle, you cannot even calculated MPG, and gasoline was about 1.50......
Now I have a 370Z which is just as fast and gets 20 MPG....
The Z/28 still gets 8 miles to the gallon at 4.50 a gallon ...
We actually have it really good with the power and MPG of the 370Z...
