GM, US car sales slump but Fiat Chrysler surges
General Motors reported Tuesday an 11-percent plunge in auto sales for the third quarter of 2018, confirming analyst expectations that North American car buyers were tapping the brakes after a robust first half of the year. Its sales surged, fueled by demand in Jeep SUVs and Ram trucks. The recovery from catastrophic flooding caused by Hurricane Harvey boosted auto sales this time last year -- making this year's early fall numbers look even worse by comparison.
