2000 Oldsmobile Silhouette-minivan- 3.4L V6. My parents had me drive it my senior year cuz it was the safest car. Didn't pay much attention to mpg then, but it got like 16-17 mpg.
Then I got the car I'm driving now, 1996 Chrysler Sebring Convertible. 2.5L V6. The power and acceleration difference is incredible haha, man could that minivan accelerate!
The Sebring gets about 17, but with mpg in mind I can get almost 20 and that's mostly city driving.
