I'm 53, bought my first new car in July of last year--a 2012 Base Fit with Manual. Love it. (replaced my 1998 civic manual, which son took/bought).
1. Gas mileage. Wow. EPA rating is completely off if you give a little effort. I average 40-42 mpg, depending upon traffic volume and temperatures, on a 41 mile round trip commute (8-10 of that is city driving), albeit I'm before and after rush hours during the week. Even on long, 5+ hour trips with cruise control at 75, it gets 35-36 mpg.
2. Low maintenance. I am at 11,300 miles on odometer, and still have 10% of oil life remaining before my first oil change.
3. It's a honda.
4. It isn't a hybrid. Our last new car (not "mine") was a '92 AWD Previa that we took to 360,000 miles (the imminent birth that we bought it for was driving it when it gave up the ghost). If I had to bet (and I am), the odds are better for a non-hybrid to hit that high of mileage. Fits with the concept that if you are going to buy new, you should plan to drive the car until it dies.
5. As others mentioned, it is fun to drive (but "fun" can conflict with mpg!)
6. If you have another couple for a night on the town, or for a 600 mile drive, it holds four comfortably--even with a week's luggage. In fact, the back seat will fit three slender young men who are six feet tall for short (20 minute) trips when they are home for holidays.
7. Can't personally compare with the Fusion, but the visibility is great. (but, hey, I was driving a '98 civic . .. )
8. N.B.--the 2012 base model does have cruise control.
9. Great road car for a couple. Wife likes riding in it better than her 99 Civic when we do weekends.
