Quoted from burningman:
My Dad bought this 6MDM in December of 1979 to keep me out of the 7-11 down the street. It was in the same location in his house for 39 years. Never moved. Never stored. Over the years, we would shop it together.and have always kept her running. He is moving and the game has now passed down.
Great story. Enjoy it. I know one 6MDM that will never be for sale!
