2010 Mercedes-Benz E-Class E550 4dr Sedan (5.5L 8cyl 7A)
The E Class car has always been a "boost" to the MB line of vehicles...but the new E550 is a quantum leap. Fantastic is the one word to capture what describes this car. I traded a 2007 bmw 750i, and the Benz shuts it down in every respect. I recommend it - unqualified.
The technology (that all works) and the responsiveness of the engine. The handling is flawless, as well.
