Hello, I'm just wondering what the following paragraph means: "My test car was fitted with a Stuart. The Stuart's ability to accelerate and brake without causing my champagne to fall over was remarkable, and in direct contrast to the Gary that was installed in the Maybach. The Gary hustled. If you're in a hurry you need a Gary. The Stuart drove like a Buddhist butler." Sourced from:

I don't understand what Stuart and Gary refer to in this case; I'd guess some sort of engine but I'm not sure and not too technical. I've tried searching, but the names are pretty generic and I've not been successful.Thanks in advance.
