The CC and Bosch use 304 SS. Close enough. Liebherr uses 430 SS. Which is a little darker and magnetic. 430 uses a "rolled-on" finish while 304 uses a "polished" finish. The grain looks a bit different. KitchenAid Micro built-ins usually use 304 and freestanding usually 430. It depends on which hood and wine fridge you buy what kind of SS it will have. Generally, more expensive appliance = 304 and cheaper appliance = 430. But there are exceptions. Liebherr is quite expensive compared to most fridges but cheaper than many built-ins.

Yep. A 1938 Ford, 2 door sedan; Bare, but polished stainless ateel. Only a few were built as demostrators and show cars. Neat picture!

The other option is to just get over it. :) A kitchen is a workroom. Most people prefer to choose best in class from many different manufacturers to ensure their work room works efficiently. No manufacture makes best in class in each category, so if you choose the best functioning DW, you will probably end up with a different brand range and a different brand fridge anyway. As long as everything IS stainless, it's fine. And, there are plenty of people who even mix stainless and non stainless successfully. Anyone who comes in your home and turns their nose up at coordinating stainless appliances that do not necessarily match needs to be thrown out of your home.

I should have said although we have a mid-high quality 'stainless' stove and fridge - the finish stains. It easily gets stains (not dints or scratches) that do not come out. Concentrated cleaning only leads to permanent degradation of the finish. "Stainless" sinks and countertops seem to be the exception because they scratch up overtime to develop a butler's patina. I hate any stainless finish on appliances. It is a gross trend that has got out of hand.
