Hello and welcome !
You are lucky men ! Living in Barbados Island, and driving a Civic, I dream about that
Ok, time to be serious... Her's the best place to learn all about the civic. Opinion are divergent about the I-shift box, people like or dislike it, so if it's possible for you, the best thing to do is to have an extended driving test with it.
Look at the Wiki database for the various infos about the car and use the Search function to found specific forum threads.
And if you need help don't hesitate to post a new Thread
