I assume you took a good look at the regular Civic before deciding on the hybrid. As far as the trunk size goes it shouldn't be too much of an issue; its got good height and loading is easy. It is completely lined including the inside of the lid. The rear seat doesn't fold, but I'm sure you know that already.

The "auto-stop" feature takes a few days to adjust to. I found pausing a split-second after releasing the brake before hitting the gas, eliminated the shudder, just as Kristian mentioned.

Your new car has several neat features not found on the regular Civics. The automatic climate control is great. The interiors are more up-scale in my opinion. You will enjoy the great gas mileage. 50 mpg is easy. With the techniques discussed here you will no doubt do even better.

Enjoy your new car!!
