Decided to try Zipcar one more time as I had a bunch of meetings today in the Valley. The car was there and the only minor hiccups were a)it was not on the expected floor of the parking complex and b) it had less than 3/4 of a tank of gas (you’re supposed to leave it at least 3/4 full when returning the car).
So, Zipcar is now batting .333 in my book :)
