I've driven this car over 1200 miles now and can report further details:
Hiway mileage is pretty good; but in mixed-type driving, any amount of city traffic will pull the numbers way down.
For example, in a 150-mile interval including about 30 miles of in-town or city traffic, I'm seeing only 26-30 mpg.
The radio reception on AM is quite weak.
Don't know if that's a fault of this particular car or if it's a general problem with the built-in antenna.
Overall, the car drives and feels great.
