It's a reliable clean car. I prefer not to rent for anything shorter than 24hrs. Additional miles are $0.75 per mile. It does not have a hitch to be able to tow a trailer, etc.
City 20mpg, Hwy 24mpg
Please take photos of the dash (gas/mileage), and exterior (all sides) of the car. That way you have a record of it. You are responsible to refill the gas that you use - if not, you will be charged for it.
When using RelayRides to rent a car, and you are very close to the time/day that you need the car, my advice would be to reserve 3-4 cars for the time you need it. That way, when the time comes, you have at least 1 or more reliable options. And just decline the others. FYI - Until you actually 'book' a car, someone else may rent the same car before you book it.
The way RelayRides works is: you request to rent a car, then the person approves you to rent their car, then you 'book it' (which is the actual commitment to rent the car), then I send you the address of where to pick the vehicle up.
