 In 1987, Peter Mehegan introduced a tradition that continues as a symbol for "Chronicle" viewers, and fans of "The Main Streets & Back Roads".Mehegan and his wife kept a rotting 1969 Chevrolet Impala V8 in their backyard garage after inheriting it from an aunt.Rather than have the car decay and get hidden by all the weeds growing in the garage, Mehegan set about to get it restored, hiring auto body specialists that spent months bringing "the old Chevy" back to life.
