The autohauz in the above reply has about the best price around.Mine was only 41 for my 300SD.I installed it with the hood on the car and it worked fine.Just make sure you get the right 3M adhesive.It tells you right on the can what its designed for or ask anybody at the auto supply shop and they will direct you to it.Just be careful if you try doing it on a windy day,stuff goes a long way when it goes!
