Bad pic of STS-V diff

Sorry this pic didn't come out too well. All I had with me on this trip was the camera on my cell phone.

There was a STS-V and a XLR-V on a display stand that you couldn't get to. There was another STS-V setup in this kind of tunnel leading to another display. This V was setup to show the engine, the front/rear suspension. The show was packed, so I didn't have much time to get on the floor and snap the pic. I have no idea if this car even was a production version.

Interestingly, the STS-V and the XLR-V are being exported to Europe, but not the CTS-V. So no CTS-V on display.
