You're right. When I was looking for an FE car I just used the EPA estimates so I thought I needed to get a CRX HF, Civic VX to get insane mileage. If I had known that parts were so readily available I would have just bought a Civic CX or the CRX DX (in hindsight, the two-seater wouldn't have worked, so ignorance turned out to be a blessing) I found. I still would have averaged 40 mpg.
But, the Metro still works for me. It just needs a little more TLC.
