I have a 02 that I bought in 2001. I have over 115,000 liles on it fortunatly I travel a lot or I would have 200,000 by now. I live in LA so my city driving is hard to calculate often I'm stuck in traffic, I do get 25 MPG on trips and have actually driven 460 miles on a tank.

Mileage on my 05 is 19 city and 28 hwy. This is actual fill up with gas since the onboard computer seems to error at least + 1/2 mpg extra than actual.

Driving a 2005 SC430 on a flat land at approx. 45-50°F (without snow) with top up, filled with premium:
Highway average speed 45 mph gets 32.5 mpg
Highway average speed 55 mph gets 27.5 mpg
Highway average speed 65 mph gets 25.0 mpg
city stop&go average speed 18.3 mph gets 16.5 mpg
Thus you increase your gas mileage by 10% by slowing from 65 to 55 mph and by 30% by slowing from 65 to 45 mph. At a slow and steady 45 mph the 20-gallon tank should take you 600 miles.
