I just did a 310 mile trip around the southern part of my state recently, 90% of it on roads with a 65 mph speed limit, and had no issues at all, other than CARS being too slow when I got close to a town. It easily maintained 50 mph, and I occasionally got it up to an indicated 60 mph down a couple of long hills. I also passed the 25,000 mile mark today, with no issues other than regular maintenance. It still feels just as strong now as it did when new.
The old farm house where I grew up in the early '70s is still standing, though a bit worse for wear.
This is the post office where we used to wait for the school bus back in elementary school. Still looks basically the same.
