Yup, and we have at least two flavors of them. One is a general smog shop where repairs and other services can be done too. The other is a test only smog shop where no repairs can be done. My '78 W250 at one time (before I bought it) was deemed a "gross polluter", so, I have to take it to a test only station every time, even though repairs were done so that it has below average readings now.
