I have a 2004 accord and my brother had a 2002 civic. Both cars are economical in fuel usage. But, the civic is better in gas mileage because it has a smaller engine specially in the VTEC model which is a technology used by honda to lower the fuel usage of the engine. The accord engine is much more powerful than the civic and you enjoy riding it. On the other hand, accord is larger and more roomier than civic. The sits in accord are larger and of course more comfortable than civic. I like the interior and exterior design of the accord more than the civic. One note about the civic is that the breaks are not powerful but the accord has more powerful breaks. This does not mean that the civic is a bad car. I am just telling you the differences between them. Of course you can not compare these two cars because you pay more for the accord and you get more features in it. But, both cars are nice. If you have the budget for the accord, do not doubt about it.
