 The consumer magazine decided to conduct the survey after several consumers who wanted to buy a plug-in car reported to the organization that some dealerships were steering them toward gasoline-powered models.The survey found that not all sales people seemed enthusiastic about making PEV sales; a few outright discouraged it, and even one dealer was reluctant to even show a plug-in model despite having one in stock.And many sales people seemed not to have a good understanding of electric-car tax breaks and other incentives or of charging needs and costs.
