Guess I'm lucky?
But I did replace my original speedo cable soon after I got this car back in '97 or so...
I've maybe put on 30k miles on it since - it doesn't get driven that often.
It is kinda unnerving to put down a 4th gear run though as you see the speedo sweep past 100mph, and you're sitting inside going no where on the dyno runs...
