I was at the dealer picking up my V today and decided to look over the new V2. I found in the trunk a nice solution. They have a mini compressor mounted in a styrofoam holder screwed down to the floor of the trunk where the spare would go. I called Luke at Lindsey and there are three part numbers for this. I don't have my STS-V back yet so I don't know if our cars have the same rectangle hole on the center of the trunk floor for the long threaded adapter.
