Can't tell you how mush,, this will only be available at the dealer. It may have an effect on the radio reception.

This is a common problem and has recently happened to me. The Benz dealer will want to sell you a whole antenna at a small fortune, but on ebay you can purchase an E320 antenna mast cover kit for around $35.00. This comes with a new rubber mast and a gasket for the base. All you need is a small allen wrench, remove antenna base from car, pull what is left of old rubber mast out of the base and using a dab of liquid soap for lubricant install new mast.
