The best mechanic I ever had kept my ‘98 Subaru going past 200k miles. Once during a repair I asked him to do an inspection and tell me if there was anything else I should replace. He told me not to do that, and that any mechanic would always find something, but not necessarily the next thing to break.

He said it better using an expression I hadn’t heard before or since, something like “don’t go looking for goats when your herd is already with you.”
