He who smelt it, dealt it—that’s usually the carpool rule. However, a group of Ann Arbor scientists says those noxious fumes in your car are coming from the materials used in the cabin. Michigan’s Ecology Center posted a new Web site, www.healthycar.org, that rates new vehicles according to the levels of possibly toxic gases measured through their testing. Worst on the list? Nissan’s Versa, along with the Scion xB and the Kia Rio. Some of the brands performing best in the test were Volvo and Honda/Acura. So join us, won’t you, in researching toxic gases and losing the bit of joy that new-car smell used to bring.Versa, Aveo, Rio Toxic?
