People were busting out all over last week, but one of the biggest spring bargains of all was indoors—the New York International Automobile Show. There, for the price of a movie ticket, you could ogle the brightwork, peep under the hood and, like the boy easing into the Daimler sports car at the left, get behind the wheel of any of 300 models from nine foreign countries and the U.S. The show's chief appeal lay in its diversity. With American compact cars cutting into imported-car sales, there was more emphasis than ever before on the kind of variety—from $1,000 midget cars to $27,000 limousines—that has given the foreign automakers a permanent foothold in the U.S. market.
