I rent here and zipcar, here the cars are cleaner / no doghair/ and price is cheap about 10-11 bucks per hr, I saw some people complaining about refilling the gas, you can go to any station and pay from your pocket, keep receipt they pay it back to you! I like the flat rates they have for evenings...
What I hate about car rental is that you MUST return car to the lot you rented... many times i go to downtown and have to pay 15bucks parking bcuz i cant just return the car to the lots there, i hope this will change and they could even charge some extra fee for returning to different locations, it would be still worth it
