Found this amazing get-away car idea from Martha Stewart. It's a minty hued vintage Rolls-Royce decorated simply with a garland of greens, roses and filler. Of course, you can't forget--the "Just Married" ribbon on the back side of the trunk!
This is a stylish way to send a message of your nuptials without a lot of garish fanfare. Also, if you're going to be decorating the car, be sure to check with your local restrictions concerning non-vehicular embellishments. You don't want to cause an accident or get pulled over and ticketed.
Who else is in love with this idea?!
