Coals to Newcastle? Ice to Inuits? Cars to California? Even in a region where the freeways and surface streets are teeming with vehicles of every stripe, Southern Californians love to get together to ogle the latest wheels. At the Los Angeles Auto Show, which continues its 10-day run through Dec. 10 at the Convention Center downtown, about 1 million visitors are expected to check out the 1,000 models on display. Twenty-one cars and trucks are making their worldwide debuts at the show. Here are three vehicles that stand out from the crowd -- one a concept, two heading to showrooms and all illustrating their manufacturers' new design themes.
