Okay so the CTS-V may be the Hennessy V650, but it is the station wagon version..... The V650 CTS-V costs $79k, the GTR stock costs $81k.
The time for the CTS-V seems rather slow for what it is, as does the GTRs(MT recorded a 11.2, which is alot faster time, but the trap speed of that run and this run are about the same)
