I can tell you Ive seen as low as 26 mpg. If you use the hvac system it may interrupt auto stop so if you are stopped a lot this will easily lower your mpg by 10%.
If I had to pick a car for you it would be a prius as they are perfect for stop n go city driving. Hondas like to rev and run. I curse mines at times for being slow, but it is easy to handle for extended driving over 70 mph and breaks 50 mpg. 0-60 is just 12 seconds.
