We are definitely experiencing the zenith of the development of gasoline-powered IC automobiles, and the AMG Mercedes is right there up front. Pretty amazing, really; a supremely safe, everyday usable, comfortable, reliable, well-mannered sedan that weighs over 2 tons and in showroom stock trim would absolutely walk all over any muscle car from the late '60s heyday, and beat most sports cars, including most all of our Porsches, around a road course. Those Germans are something else.
