My Mazda is around 3,000 @ 70-75 or so. 18" wheels, 6 speed manual trans. It's got a 3.35 gear in it. I drive 120 miles/day, mostly highway. Less gear would kinda suck actually. I like the performance - it goes when I want it to and seems to cruise pretty effortlessly, even if it is a little higher RPM than your average econobox. Mileage is OK for a turbo 4 banger, usually 25-26 MPG depending on how much I can stay out of it.
OP would probably be unhappy with anything less than 3.23 if there's any spirited driving involved. Compromises like converter slippage, vehicle weight, tire size and cam - all can be made better with gears.
