width=400With $1.7 billion already claimed by consumers, the NHTSA is preparing a wind-down of the CARS rebate program, reports Automotive News. Based on dealer sales and other surveys, the NHTSA can make a pretty good judgment call about when to end the program, reckons Transportation Secretary Ray LaHood. I know dealers are frustrated, but they're going to get paid. LaHood said the program's high rejection rate is due to the huge demand and dealers' failure to fill out claims correctly. Dealers, meanwhile, are far more likely to blame the rampant delays and rejections on the NHTSA's failure to have their shit together. Either way, it sounds like just about everyone is ready to be done with Cash for Clunkers.
