We have a old Kitchen Aid (probably 30+ years old) that works great but the rubber coated racks will split and rust. I was lucky enough to find a replacement for the bottom but I have had no luck finding one for the top and ours is starting to get bad. They don't last forever. All our appliances are original to the last remodel which was done at least 10 years before we moved here and that was almost 30 years ago. The stove and dishwasher won't be bad but the frig is a counter depth built in with the cabinet facing. That will be the tough one. Huh, I wonder why the lower grate was off?
