Victory Toyota of Midtown in Chicago has more than a dozen Priuses lined up like a used car lot, but they're not for sale; they're waiting to have their catalytic converters replaced after the old ones were stolen. "Given today, we've had five come in for the same thing, catalytic converters just being sawed off," said David Meraz, owner. So many hare stolen the dealership can't keep up with demand. Meraz said the wait for manufacturers to send parts can take months.
