Ford Focus, Taurus, and Mercury Sable. Those are the first ones to come to my head. All three are reliable and are not gas guzzlers. I originally wanted a Taurus or Sable, but ended up with the Bonneville (which I'm very happy about)
Damn near ANY mid-late 90'* Civic will get 30 if not 40 MPG highway. Civic, corolla, etc all do well in Mileage... Japanese small cars can't really be touched when it comes to mileage with respects to most domestic offerings.
I do mostly highway:
That'* 27.01mpg to date. MPG is getting better as the weather gets warmer, but it'* still pretty crappy.
Granted, I could use new plug wires and a distributor cap/rotor, O2 sensor, etc, but quite frankly this car isn't worth enough to even justify that.
I'd really like a granny-geared beater-Bonneville right about now.
So YOU have one of those too? Ill have to post mine sometime.... many many pages long.
