I dropped my key between the passenger seat and the transmission tunnel in my 300E. Using a wire I tried to fish it out with the seat in various positions. After fifteen minutes I gave up and will attempt to retreive it tommorrow. It is now stuck under the seat rail. This is not the first time I have done this. Not long ago I dropped a credit card in there and it took me almost 30 minutes to remove it. What is the best way to remove objects (coins) from this area. Thanks.
