Someone posted an interesting tale on this forum awhile back. As I recall, a customer brought his newly-purchased pre-owned 600 (I don't remember if it was an S or SL) into the the guys shop, complaining about a lack of power. Shop owner could hear the umistakeable sound of 4.2 liter under the hood. Priceless reaction from the car owner when he learned he had just bought a rebadged 420, at a 600 price!

Happy Motoring, Mark
