efficient -- 50+mpg. reliable -- only 22k miles, well maintained, never any problems. not very clean. usually available for periods of a few hours only (this is my only car and i use it too), but you're welcome to ask for longer so long as you understand i will probably say no. the calendar is rarely accurate -- i am sorry, it is just too much work to update since i use and loan my car pretty extensively.
priced well under market value because car sharing is awesome and i don't want to deny anyone because of price. i have been car sharing for years (though just started with relay rides) and would be happy to provide references.
