BIFL stand mixer with replaceable parts

Looking for BIFL stand mixer that I don't have the intention of replacing or upgrading unless it fails catastrophically. KitchenAid stands out as it's more versatile than the other more expensive offerings even if they are more powerful (I'm not doing much if at all anything low-hydration or even large batches for a big family). Did some brief search, seems like bowl-lift model and one with DC model is recommended. Then I want one that has replaceable (preferably cheap and accessible) parts and is self-serviceable. It should also be available at some big retailers (I have access to a variety of gift cards for big retailers which I'd like to consume).

Looking at this guide from KitchenAid, it seems it's not up-to-date as at least one of the few ones with DC motors are discontinued? I don't think the Commercial variant is available from big retailers and I would rather purchase one with DC motor that is new and not from Ebay (I would also keep looking in the back of my mind but don't have good experiences with new appliances).

There's only one part that needs to be replaced perhaps every 5-10 years or so? I read something about plastic vs. metal tht was apparently a myth and not a good indicator of whether a model is considered BIFL.

Any other tips are much appreciated.
