Vehicles sharing a platform is not a simple rebadging. The Chevrolet and Holden are indeed more or less the same vehicle, but the Isuzu MU-X is not so much related it seems... or is it?

I suppose it is rather like the Saab 9-3 based on the same platform as the Opel Vectra or Chevrolet Malibu, though that the car was still conceived by Saab in Sweden and not really related to these other cars.
