Yipsy I have a Sub Zero 642 (no longer in production) in my house, was there when I bought the place in 2023. Since it is built into the wall, appears to be the original one. Works well, but I'd prefer more of the options of current fridges. Not sure if I will repair vs replace when it goes bad. The reputation on them is good. I just looked up the price and not one for the everyday family. Geez.
BTW, the Sub Zero is stainless steel and not magnetic. I like to use magnets on the fridge to hold all the clutter.
I put in a Samsung into my house in VA before I sold it when I remodeled the kitchen. Bought as scratch & dent from Lowes. Worked well.
