What Kind of Mutt Do You Drive?

I like to follow design trends, some of it relates to my job but mostly it's a hobby. A while back I noticed Mercedes-Benz starting to resemble Honda Accords. Recently I saw a Mercedes-Benz R-Class which looked like a Toyota Matrix, that in turn bears a resemblance to a Ford Focus.
It's as if automobile manufacturers were behaving like dogs, which when left to interbreed indiscriminately tend to revert back to two or three prototypical mutts.
