Prius models from 2001-2006 had the largest repair price gap, mostly because Toyota sold its iconic green machine in fewer numbers back then. Newer, higher volume Prius models have cut the disparity considerably, but there is still a gap. Other hybrids cost more to fix as well. Hybrid models of the Civic and Camry cost 3.8% more to repair than their battery-free siblings. This news probably isn't going to effect any eco-minded buyers' decisions to purchase a hybrid. But people who buy hybrids because they want to save money on fuel have to factor in higher sticker prices, increased repair costs, and a battery pack that may one day need to be replaced.
