We have a 2006 Ford Escape Hybrid, plus a 99 Mercedes Turbodiesel. The former consistently gets 27-30 mpg around town, and we really like it. The latter consistently gets 30-33 mpg on the highway (even at over 110,000 miles on the odometer), and can run on veggie oil eventually if we decide to go that way. It's also a great performer with the turbo...accellerates like crazy, doesn't lose power up in the mountains.
We're really happy with both cars. Especially these days...
