This is America, the land of endless highways that criss-cross an enormous empire. The road trip is an important part of our cultural heritage. It's no secret that some cars are better suited for this than others. You know that very well if you've experienced the difference between how a Smart ForTwo and a Jag handle the highway. We've included cars from all price points on this list. Some are here for their miserly sipping of petroleum. Some for comfort and luxury. And some simply because they're iconic, and the list wouldn't be complete without them.
