Big doings are aleady underway for the 2015 New York International Auto Show, and it promises to be one of the biggest and most important shows in the Big Apple for years. The show gets underway at Jacob Javits Convention Center, 11th Street between 34th and 40th Streets from Friday April 3 to Sunday, April 12. Hours are 10 a.m. to10  p.m. Monday through  Saturday and 10 a.m.to 7  p .m. Sundays. One of the most awaited world premieres in decades will happen this year will be the debut of Cadillac's long-awaited large luxury sedan, the CT6. We have also heard that another long-anticipated car, the next generation of Chevy's hot Camaro, will also happen this year in New York's show, but that has not yet been confirmed by GM. Another car that is due to be unveiled, the next generation of th Chevy Cruze, may or may not show up in New York, but with its introduction not far off, New York, since it is the last American "big" show of the season, would also be a logical place to hit the show floor for the first time. We've already gotten pictures of perhaps one of the most important models to be making its world premiere: The all-new Nissan Maxima Luxury Sports Sedan.. No word on specifics yet, but we are expecting a dramatic interior and the most eye-catching styling seen on the Maxima in years.  This is a total redo, if the pictures don't make that obvious.
