Just got back from a 2000 mile trip........
and averaged 25.4 mpg.Very well-built and comfortable road car.I did a search for this and didn't find any posts about this so here goes.When I unlock the doors,I hit the button a third time,and it lowers the windows until you let off the buttonI hit it once,twice,and hold it down.........mine is an SE and thought it may allow you let the inside cool down on a hot day.Also saw 3 Challengers on I-75 going south on a private hauler..........JB.
