I wouldn't mind better mpg, but I know the trade off would be either luxury, performance or money in the bank account, or all of the above.

I got around 21.6 mpg overall avg, and easy to get around ~25 mpg cruising around ~70mph on the freeway.

Our G's gas mileage is PATHETIC.
REALLY pisses me off.
