New vehicle sales will not rise substantially as the US economy recovers, unlike past economic cycles when consumers' pent-up demand boosted results, a top official with General Motors said on Wednesday, according to Reuters. "We will probably not find a high degree of pent-up demand," Paul Ballew, GM's executive director of market and industry analysis, told Reuters. In past economic recoveries, "you got the abnormal spike in vehicle sales," he reportedly said.
