Our San Francisco fleet has a plug-in electric hybrid that can zip over 100 miles per gallon.
As a Zipcar member, when you reserve an SUV/AWD (just in case, that's a Sports Utility Vehicle with All-Wheel Drive) you also get free parking at any Sno-Park location and all Northwest National Parks, and free admission and parking at Oregon State Parks. After you've joined, email (firstname.lastname@example.org) a copy of your most recent Alaska Airlines boarding pass you’ll get an additional $25 FREE driving! (That's a total of $75 in driving credit!) who is eligible to become a zipcar member?: http://www.zipcar.com/how/faqs/who-eligible-become-member other frequently asked questions: http://www.zipcar.com/how/faqs
