Last fall I had not yet joined ecomodder, and I was getting right about my EPA average MPG of 24.
I just finished rebuilding the suspension on my car and took it in for new tires and an alignment. For the first time in a while it's entirely mechanically "right" - today on the way home from class, I had a 10 mile drive through traffic with two fairly long stoplights, and I averaged 39.5mpg, using engine-on coasting in a car that only gets about 30-32mpg in steady-state cruising in top gear. 65% over EPA!
