99 mpg !!!!
On my way to work today I was cruising at 55 mph in overdrive and I looked at the DIC and my instant MPG read 99 MPG. 
Of course this was coasting down hill with my foot off the gas.
If only it was true. So far I've been averaging 20 mpg which is pretty darn good for a 350hp automatic sports car if you ask me.

Not putting your foot into it enough... try 9 to 13 mpg

Exactly why I don't even bother with displaying the instant MPG readout. Mine is usually set on Average MPG.
I have a pic taken with my camera phone on my trip to Bowling Green of the car's instruments with the tach at 1600 RPM, the speedo at 72 MPH and the display showing Average 31.3 MPG. Sent it to a friend of mine who was always bragging about the MPG of his VW Jetta. He about fell over.

You guys have it good. I look at mpg all the time with gas at $10 a gallon. Mind you I still often see 3 mpg
Love it. Even I've never seen 99mpg

Go back to that same hill going in the opposite direction and report the new numbers.... I often see 4 mpg.

If you're getting 20 mpg in city driving, that's pretty good.
