10,000 mile update. The car runs great. Everything works as it should.
Avg mileage is about 3mpg less than the old '17 I had (23 vs 26), so I do think the tuning is different in this car. Not complaining at all, just an observation. It still can hit 30+mpg on the highway. Can definitely tell the difference in drivability and response when in GS mode.
