I can't put my finger on it
And yes, I know that Kenmore labeled appliances got extra QC time on the line, but somehow it just seems as if the Kenmore appliances built by Whirlpool were just plain better - in design and durability.
I don't like Whirlpool, but there's no question they did some great looking design back in the day. Today, of course, if I had to buy from them, I'd buy the Roper or Estate brand - same stuff, just much less expensive. You're really just paying for the name on KitchenAid and Maytag, now.
As to discouraging BOL sales, boy oh boy did they ever. I had a whale of a time many decades back getting them to sell me a Galaxy for a friend who had to buy new (insurance claim) but had very little to spend. Succeeded, but only after getting the store manager involved and applying what scant charm I possess.
