Sorry Frog, I mistyped earlier. Select an object, open the propoerties panel, select the "Edges" tab (not Render), then check the boxes by "Silhouette Edges", "Unshared Edges", etc. Mess around some in this panel and you can get some good looks.
Check out this free tutorial far a wireframe render of the McLaren. Rendering the edges is also a great technique for showing off your models.
