The county "discovered" this fleet of no-mileage vehicles after reading about them in a Spanish-language newspaper there. Most of the misplaced motorcade is made up of Toyota Prius hybrids whose warranties either expired with very few miles on the odo or will very soon.The county, as you probably guessed, is looking into how it lost so many cars. The leading theory is that they might be part of Carlos Alvarez's time as mayor. He was the mayor during the period the Toyotas were purchased, but a 2011 recall election successfully removed him from office. Apparently the voters "felt, among other reasons, that he had been behind multiple acts of misappropriation of funds."
