I have the car down south for vacation, ~350 miles one way. We got 44 MPG. Running the A/C on max with a top speed of 70MPH. I tried to neutral coast when possible and kept her rolling slowly when we hit traffic. I wanted to do some more aero before driving such a distance but I didn't get enough free time. After next week mostly all of my free time is going to be spent fixing up the car.
I need to do some body work and improve the aero at the same time on the rear bumper and the passenger side front fender.
