[P] 3D Cars Dataset used in disentanglement literature

Does anyone know where to obtain the "3D Cars dataset" used in the disentanglement literature? e.g. this recent paper: https://arxiv.org/abs/1905.12614 (landing page), Figure 1.

I've basically traced the citation breadcrumb to this original paper: 1 (warning:pdf) with associated download 2 (WARNING: large .tar file) which only provides the basic 3D CAD models but not the more advanced latent factor variations shown in the linked Deepmind paper above. Would be nice for reproducibility of results.
