I've heard that you have to break in the engine. And I am debating it with co-workers. I'm getting my car on the 22nd and am planning on taking a 6hour roadtrip in it back home. Would that be a good choice? My co-workers say you have to break it in, and drive at varying speeds for the first 500 miles. I figured car technology has increased and that wouldn't be an issue. Any comments?
