GMC Superban LS 1993 Used Automatic Gasoline mileage: 300 KM or more Royal GMC for sale, model 93 Mileage approximately 350k The gear is leaking oil, I don't know the reason, but maybe the parking is one of its causes. The rear tire needs changing. And maybe the battery needs changing. The passenger door trim needs fixing. It has been parked for more than a year. Before I parked it, it was running well. The sale is easy, God willing.
