We have a 20+ year old Sub Zero built-in refrigerator ( it was iin place when we bought the house) . While it continues to function, we want to replace it. , with a more modern/ efficient unit. Our unit does not have a freezer module.
I have read many, mostly Negative reviews on the current Sub Zero models. Is there a built in manufacturer series that other users would recommend? I sure would appreciate any advise, before making a ~$7k purchase.
