The honeymoon isn't over yet
 My wife and I have come back from 3 day trips and continued past the house just because we didn't want to quit driving this car.  Average gas mileage is about 21.6.  You can get 26 mpg rather easily just by keeping the rpm down around 2500, (boring).  Beyond 3000 rpm the sound is kind of like the Teutonic scream you would expect from an 11.5:1 compression ratio engine tuned to deliver more than 100 hp/liter.  The ride is firm like a performance car, but very comfortable.  Noise is not a problem either.  It is noisier than a limo in all the right ways.  The wood dash trim improves the interior.  The stereo is first rate.  It has a dipstick, no run flats, and hydraulic steering.  Brilliant!
