I wish I could get this vintage 1960 Whirlpool Imperial Mark 12 washer, but $600 is way out of my price range.
They should consider about lowing the price since the seals will more than likely will need to be replaced, and these old Whirlpool/Kenmore belt drives are good machines, but replacing things like the tub will be a huge ordeal, and if you bump the air dome, you will have to fix that since it can cause the washer to leak.
If it were paired up with it's matching dryer, maybe it would be worth $600, but even then that is a little too much.
