Alternative-Fuel Vehicle Recommendations?

Ellen Spertus asks: "My husband and I lease a pure electric GM EV-1, which we love, and need to replace our second car, a conventional Honda Accord, which recently died. We'd get a second EV-1, but GM has stopped making them. I haven't been able to find any available all-eletric car with the range (>=50 miles roundtrip) and speed (>=65 mph) that I need. Does the Slashdot community have any experience, wisdom, or advice on choosing an alternative fuel car?"

"I'm currently considering:

• Toyota Prius, a hybrid sedan
• Honda Insight, a hybrid two-seater
• Honda Civic GX, a compressed natural gas (CNG) powered sedan

We test drove a Toyota Prius today, and it seems like a nice car. It's said to provide a quieter and more comfortable ride than the Honda Insight, and it uses pure electric power at low speeds. The Honda Insight, on the other hand, has better gas mileage. I could refuel either at regular gas stations. The Honda Civic GX would need to be refueled at special stations, but there are many where I live and work, the San Francisco Bay Area. The GX is the lowest in emissions, which would qualify me to drive alone in the carpool lane. All of the cars are about the same price, around $20,000 new. Used cars are also available."
