OGR Story

Our family arrived in Mount Gambier in 1956 (my father was only 7) and my grandfather Owen Gwilym Roberts (OG) built one of the most dynamic new and used car businesses in the country.

Over the 60 years OGR has been in business, we’ve lived by the philosophy of having quality people providing quality vehicles, service and products. We offer new Kia, Mazda, Nissan, as well as an impressive range of used vehicles.

Our highly trained Sales team are dedicated to matching you with a vehicle to suit your needs. Whilst our finance and insurance department can show you how affordable a new car really is.

Our award-winning Service Department and state of the art Panel and Reconditioning Centre are dedicated to maintaining your next vehicle to the highest standards.
