Yeah, plus even the stallion has that same type of logo (at least it did in GTA3) and all the "spinoff" cars still keep the same name. If it was a spinoff of the Kuruma it would be called the Kuruma.
I like how the Hermes sounds and looks, but I like the hydraulics of the Voodoo. I dunno why but for some wierd reason I like the engine sound of the Oceanic, which also is the saem sound as the Voodoo....
