You've not looked then, because plenty of American and European cars have
that feature. Usually the smaller cars with smaller low cost engines. Take
a look at the list of cars from the Gates link I posted and you'll see
plenty of them listed.
You won't find belts on most of the V-6 engines though. Personally, I'd not
buy a car with a timing belt, but they do fill a need.

Most cars (including Asians) are getting away from belts, but they have
existed on many cars over the years.
