Looks like yours were 100%. Sorry for your losses. I remember reading on DU a few years ago a fellow said he always bought older used cars, used them until they quit, then bought another. He figured that all together, his cost was less than repairs to keep one of them going. I had that situation with my beloved 1978 Honda Accord with 230,000+ miles on it (I bought it new). It hadn't cost me much to keep it running but when it finally died, the repair costs would have been more than it was worth. So, I bought a used car for $750, ran that for a couple of years (without repairs) until it finally died, then I bought a one-year old car which is now 11 years old and running just fine.
Side note: It was summer when I had the hauler tow away my 78' Accord. I picked flowers from my garden to put under the windshield wipers to show my appreciation of the twenty years of service the car gave me. I asked the guy what was going to happen to the car. He said "it will become an organ donor".
