Creating multiple Objects from same AssetBundle Asset

I'm trying out AssetBundles for the first time and am confused as I try creating multiple instances.
The AssetBundle seems to just spit out a reference to the previously created instance of that GameObject, but what I want to do is create 3, let's say cars, from my Vehicle AssetBundle.

I can Unload the AssetBundle in between each LoadAsset but that will considerable slow down my system.

Any help, or should I go about creating my cars another way?

Thanks
