Ok, I agree with you there.
We are back to the point that everyone has to consider what they want and how much this extra is worth to them.
Since I have never bought a complete kitchen before, I cannot judge. In our house, there was already a kitchen unit installed that is about 10 years old. It is fully equipped with Miele appliances. They are really great. However, the refrigerator broke down a few months ago.
We will probably buy new appliances and cabinets in about 10 years or so. The countertop is made of 6cm granite including a matching backsplash. Everything, including sockets, is fitted precisely down to the millimeter. That is amazing. Therefore, the countertop will probably stay in place.
