Finally pulled the trigger. Picked up a 2016 Honda Civic EX-T in Burgundy night pearl with Ivory/black interior on 3-11-16.
So far, I'm extremely impressed with it. Going to work I achieved 51.1MPG in extremely heavy rain, strong head winds, and stop and go traffic. In the same conditions my insight would have gotten about 60-65.
I took a trip from work to my uncles house to spend some time with my cousin, and I achieved 52MPG despite the fact I raced an Acura RSX (And chopped him, btw) who attempted to pass me on the on-ramp, and some A/C use for defrosters.
Once I got a couple hours sleep, we started up and went to LAX to take pictures of airplanes/get some food, the trip (which had a ton of stop and go traffic) resulted in 45.8MPG.
I then did a ton of city driving in constant stop/go conditions in the city while there and moving to different spots around the airport, and my average was 35-40MPG.
When our day was over, I took him home and then drove home, achieved 46MPG on the way home, despite dealing with heavy 210E traffic. This also included a 3,000FT elevation difference (uphill).
Overall, I'm extremely impressed that even with a non-broken in engine, I'm still getting 45+ at highway speeds. This was all with the tires at 32PSI (set from dealer). The car also has mud-flaps, which I may remove if they will give me 2-3MPG. It's extremely comfortable, quick, and the features in general are just nice to have compared to my insight. I can drive more than 50mi now without my back hurting, which is nice. The car tries very hard to keep MPG's around 45 in cruise control. Cruises at about ~1800RPM at 65 and roughly 2,000 at 70.
[Edit]: Before anyone asks, yes I'll be keeping the insight. I'll be driving the insight 65% of the time to work, just because of cost/wanting to keep mileage down on the new car.
Credits to my cousin Dylan for taking these pics for me. His camera is amazing, and I appreciate the time he took to come with my to LAX (then again... He asked to go but still).
