One piece of news that could bode well for future car sales, the 2011 Chicago Auto Show closed Sunday night and enjoyed a 10 percent increase in attendance over its 10-day run when compared to a year ago.  Overall, auto show tend to attract shoppers, who are likely to be in the market for a new vehicle in the next six to 12 months, experts suggest.
 "We enjoyed an opening weekend stronger than in 2010, but gave some of those gains back on Valentine's Day," said auto show general manager Dave Sloan. "But heightened interest in a recovering auto industry, coupled with a warmer-than-normal February and strong buzz in the community helped achieve the show's gains. Our closing Saturday was among the best days we've ever had. Our manufacturers and dealers had hoped to see a bump in interest this year, and they weren't disappointed."
  "But now we have to see how this translates into sales at local dealerships. If the boost in our attendance is any indicator, I predict we'll see a continuation of the increases we've been observing in monthly sales," Sloan said. The Chicago Auto Show is produced by the Chicago Automobile Trade Association, which represents the area's franchised new-car dealers.
