A $30k car? You'll pay a mechanic to fix that, it's too valuable an asset to just throw away (and even then, you see people selling cars with "something broken" that is not economical _for them_ to fix, but if you know how to fix it you can get a car cheap).
A $500-1k wash machine? Unlikely to be worth the $100-200 to bring out a repairman (because now you're looking at a $200 "discount" on a new one, which is probably much more "advanced" (if that's good) than the existing), so it gets tossed.
