DETROIT: US retailers faced competition for customers from car sellers on Thanksgiving weekend, as auto dealers offered bargains on vehicles as alluring as any discounted TV or stereo system. The mad dash for midnight ‘Black Friday’ deals at stores like Walmart and Target the day after Thanksgiving has become an annual ritual. Less noticed are the crowds flocking to car dealers. November has long been a notoriously slow month for car sales. But in recent years, car dealers have joined in the Thanksgiving weekend sales extravaganza, making November one of the best months of the year for auto sales in recent years.
