Unreal MPG
 I purchased the Prius Four on July 23.  Topped up gas on July 24th and zeroed out Trip A.  Filled up on August 4 at Costco.  Did 568.5 miles and used 8.214 gallons for 69.2 mpg.  This is significantly better mileage than our 2016 Prius Three Touring, which gets 63+ mpg.  We had one significant repair (strut) on 2016 Prius which was covered by warranty.  Very satisfied with the car.
