Dumb things,that happen at car lots....

In '73 I was thinking about buying a new Dodge van. I had heard they were going to offer sliding side doors so I went out shopping to see if this was true. First dealer I went to said "no I don't think they're going to". Second dealer said "yes they will but not for a few months". Third dealer said "would you like to look at one I have out back?" It pays to know what is going on with what you sell. The third dealer ended up getting my business.
