FAMILIARITY fails to breed contempt with Chrysler’s 300C. Even though the extroverted American has been on sale here now for a little more than a year, it still retains the confident aggressiveness that startled Australians when it was originally launched. And the new Touring station wagon version is just as startling to look at. To all of the brassy appeal of the sedan, the 300C Touring adds more versatility in a luggage area that is surprisingly large considering the custom-car roof chop and pillar box side windows. Lounging room for five, big, comfy seats and a standard equipment list that is consistent with its surprise-package status, the Chrysler 300C Touring is a king among station wagons.
