NIB 1989 KM DW
It appears to be a D&M built DW, it would be best to never open the box, LOL. $60 is about 12 times what the current value of this machine in scrap.
My former partner bought a new condo in 1980 and it had a basic D&M built KM DW in it, It was about the most miserable DW we ever used. I replaced it with a WP SHU9900 electronic DW with the tilt-out control panel after a few months. I took the D&M KM and sold it to a Lady and installed it in one her rental properties and gave her my usual 1 year parts and labor warranty on the DW. That DW not only had several problems in that first year but we ended up trashing it within 3 years after several more problems.
Afer this experance I always vowed that even if I found a D&M DW New IN The Box I would trash it.
