No, very different owners. Zagame is a very successful automotive group that focus on premium and ultra premium vehicles. They have the Victorian exclusive rights to brands like Ferrari, Lamborghini, Aston Martin, McLaren, Rolls Royce, Singer and others. They also have multiple Audi dealerships and Cupra. They have a reasonable presence in Adelaide so maybe they could take on service and sales for SA?
One of the three Grenadiers in the picture is a Black Edition wagon so they are very new vehicles.
