I signed up for Zipcar. It's possible that I will only use it to go to this one job interview (rescheduled for next Monday), and then need to buy a car to commute off the T. In the unlikely event that turns out to be the case, I should have just rented a car from Enterprise for the day, rather than wasting the $75 signup fee for Zipcar. I am uncertain about how long the interview + drive time will take--at least 5 hours, with a cautious estimate being 6 hours, and a very cautious estimate approaching 7 hours--this doesn't look like a trip to show how cheap it is to only rent a car for a few hours.
But I could park a Zipcar on Tuesday and NOT WORRY ABOUT IT if there were a snowstorm on Wednesday. I wouldn't need to pay somebody $15 or $20 to clear the snow off the car, or find a place to park it while the parking place is plowed. If I'm not the first user of the car on Wednesday or Thursday, somebody else will deal with all that.
