Is there anything unique about the kind of alignment machine a dealer uses to alignment W124's, or is it a kind that many shops use?

Because of the tire balance problem I've had, I'm wondering if I should have the dealer check out my alignment.

I've had it done by a reputable tire place that is always busy, but I'm wondering if it takes a special machine or expertise.

Both MB Indy shops I've taken my car to don't have alignment machines.

thanks in advance.
