This was my first ride, looked almost exactly like this one, in fact, maybe this was my old car?
Got 12mpg
This was my first car I bought myself, identical to this one, but my car was a four speed instead of automatic. My first mod was making the bucket seats fully recline, this was not common in car until many years later.
Let's see, after the engine rebuild and 780 carb, it got about 10mpg..
