Some years ago my brother and I bought identical cars.
My brother has not used his, but has kept it in his garage ever since and, if anything, it now looks better than new.
I have been rather busier and my car has nearly 150,000 miles on its clock.
The saleman for both out cars was called Albert and he promised that the more and faster I drove, the younger my car would look, relative to the one of my brother.
So why, oh why does mine look like a train wreck that has already happened ?
 

Because you listened to a car salesman.

Albert, huh. I happen to know him. His mechanics are Ludwig and Rudolf, and they always set the entropy on the dashboard to zero.
