GPS is great when the car runs.

Its not such a great feeling when you're looking at and expensive GPS unit on your dash, useless b/c your car is dead as a doornail. But alas, it redeems its worth when I get the number to the nearest towing service and I don't have to throw money out the window by calling 411. I love you Garmin C330. I think I shall name you Mary Poppins.
