Infiniti G20 5 SPD M/T MPG (what can I expect?)

[Lag is Free]

I am curious of the possible MPG numbers I can manage to see with these cars. I am looking to purchase one, and I'm just curious of the numbers I can manage with simply very careful driving. I've seen threads and posts that suggest that the EPA might be off and I can see as much as 24 city and 32 highway, which is just fine for me.

Have you checked on fueleconomy.gov or fuelly to see if there are others with this car posting mileage?

Also, define "very careful driving".

What's your typical usage? Commuting? Mostly city? Trip length? Highway? How fast do you cruise on the highway?
