Aided by hefty incentives and some improvement in consumer confidence, US car sales are expected to rise in July from last month but fall well below last year's levels, Associated Press (AP) reported. But AP noted that some analysts say it's unfair to gauge the state of the industry this month by comparing it to July 2002, when automakers, led by General Motors, cleared out old models with blow-out incentives resulting in an extraordinarily high seasonally adjusted annual sales rate of 18.1 million.
