Taking a page from grocery shop’s playbook, a car dealer in Belgium tried the “buy one, get one free” tactic. It actually worked out very well for them last month. The promotion allowed the customers to pick from a full range of new vehicles starting around $30,000, and then choose a second free vehicle carrying a price tag up to $18,000. Belgium’s Cardoen auto dealer’s commercial director said he had witnessed a tenfold increase in visitors since the promotion kicked off in late November.

May be GM or Ford should try the similar tactic in U.S. to move the cars out of dealers’ lot.
