U.S. October auto sales for the three Detroit-based automakers rose by double-digits from a year earlier, but results at Ford and Chrysler narrowly missed analysts' expectations.
Automakers reporting monthly sales on Friday were expected by analysts to show a gain of 12 percent to about 1.22 million vehicles, or 15.4 million vehicles on a seasonally adjusted annualized basis.
General Motors said October sales climbed nearly 16 percent to 226,402 from 195,764 a year ago, beating expectations. All four GM brands reported year-to-year increases, with Buick up 31 percent. Analysts polled by Thomson Reuters, on average, expected GM sales of 211,563.

Chrysler reported October sales of 140,083, up 11 percent from 126,185 a year ago. Analysts expected 143,536.
