We have a Honda Civic hybrid. Looks exactly like the regular Civic except it has the words "Hybrid" in small print right after "Civic" on the back.
From SF to Las Vegas on one tank of gas. Plus free carpool lane access (even with one person) and a $5000 off the top tax break. It even completly shuts off at stop lights ( no engine noise and as soon as you put it in gear, it just goes. And no you don't have to plug them in). Honda contacted us to buy the used Civic back cause they can't keep them in stock.
Once my car goes (any day now, I'll pick up some variety of hybroid car)
