Highest MPG gas combustion vehicle from the 90's.

[GasSavers_busterbrown]

I'm looking for a extremely efficient dd for my 78 mile work commute. I've been lurking a while now on the boards an would like recommendations on models built in the 1990's that get high scores for consistently operating above 50 mpgs without much modification. Civic VX's are hard to find in my area as this has topped my list for months now. Suggestions are helpful on stock models.
