Man that log book is wild. I saw a video a while back about old school mechanics who kept handwritten records of every single job they did, like 30 or 40 years of them, and people were saying it was basically a history book of the whole neighborhood. Every car, every problem, every fix, all in some guy's messy handwriting. That retiree in Tucson probably knows more about certain cars than the people who built them. Makes you realize how much stuff we just lose now that everything's digital and gets deleted.
