ur question is one that everyone who doesn't have a civic seems to wonder about.
the answer is simply this: civics have low insurance costs, are relatively reliable, inexpensive to buy, inexpensive to maintain, and inexpensive to modify.. ANY car can be modified for performance, it all depends on $.
but yeah, i'm selling the civic this summer. what will i get next? like dom93hatch, i want a turbo mr2 or an SR-powered 240sx. i'm tired of front wheel drive and natural aspiration.
