Fox at LAX rents the Prius (used to be USD 30 per day, but it is now up to USD 60 per day as it is so popular), the Honda Civic hybrid and also the Toyota Highlander hybrid. Lots of availability. Budget at LAX used to rent hybrids, but they seem to be gone in the last couple of months. Maybe they decided the resale market was so strong when gas was over USD 3 per gallon that they sold the fleet off.
