I have had my 09 Civic hybrid for 8 months and absolutely love it. I get significantly better fuel economy than the epa estimates, averaging around 53 mpg, though I drive conservatively and make a game out of trying to get the best fuel economy I can. The car's sweet spot for fuel economy is 35-50 mph (around 60-65 mpg), and driving around 70 - 75 you'll see your fuel economy drop to the low 40's (one drawback). The hybrid assist-regen system works well on small to moderate hills but doesn't sustain on large hills, leaving you with a small engine that has to work hard to get up long inclines. Another potential drawback is the back seat doesn't fold down, but it only an occasional problem.
hybrid system, engine can close valves based on power demand, which can result in short segments of getting 60-100 mpg, display is great.
move the battery pack so the rear seat can fold down.
