Hybrid rentals in Seattle?

Travel Info
I'm going to be in Seattle for a week in July and will need to rent a car. I'd prefer something with good gas mileage and am hoping to rent a Toyota Prius or another Hybrid car of some sorts.

Are there any car rental places in Seattle that rents hybrids?

Travel Tips

Hybrids are difficult to rent, you should rent a Toyota. My camry get's 35 miles to the gallon and it's a 99. So for an 18 gallon tank I can drive over 600 miles. Try that instead of a more difficult to find hybrid. Also, call around. You don't want to rent at the airport.

ANy palce like Avis or Enterprise will have these cars, you can also rent them at the airport but they will cost more to rent since they are not "Economy" they will be the next step up. Quite a few guests here at the hotel i am working at rent these cars
You make a great choice and save money on gas. You might take a look at http://www.AirZu.com/Car
