Rick,
No doubt that it is expensive, it is German (Bosch) and made using AM (Additive Manufacturing). I have tried to find the pricing but it is apparently to new to have published pricing.
Yes, 60 amps at 12 volt is just about 1 horse power, which is pretty representative of the power required to move 160 liters of water at the rated pressure and considering the pump efficiency which they claim is 60%. Sure would like to see the insides.
