Vmc 139

I need your help.  A friend want to sell a VMC 139 he has had for the last 27 years.  During that time it has been run approximately 3 hours and been stored inside his house (climate controlled room).  The condition is as follows:  there are a few scratches, three dings, the lower door hinge is missing the lower part, only half remains, this has the door cocked just a little, the coin funtion does not work.  On the positive side it still cools very good and once the coin part is bypassed crank the handle and a bottle is delivered as should be.

Is this machine worth the $600 he wants for it?

Thank you,

Mike
