On the 6.9, if it has a sunroof, open it up a crack. Everytime you walk by it throw the money you have in your pockets into the crack. When the money overflows, flip the car on it's top and empty the change. Cash the change out and go buy an SL. Crush the 6.9.

I'm not a big fan of the 6.9 as if you couldn't tell.
