I think they did a pretty good job making the car feel a little more powerful than it is.
I too have been checking my oil and I'm a little above the full mark so far. Again this is less than 2000 miles though so it's probably too early to know if I'll have an oil consumption issue.
I'm surprised you are getting 30 MPG with that commute and letting the car idle. seems pretty good. I'm generally around 26-28 MPG b/c my commute is only about 3.5 miles one way. I did manage over 36 MPG on a 30 min drive that included some highway and back roads by taking it easy on the gas. So the MPG numbers are possible - you just have to keep it at 65 mph and under.
