hmm 12 more "something" in the later car vs the earlier car. I suppose that could be 12lbs of the high-strength steel they use. Wonder where they put it.Interesting... this actually made me go out and see what my build date was: August 9, 2010. Whew. BUT I wonder if there is a structural difference or is it just the difference in the optional features availability (lane departure and frontal crash warnings)...
