Used to be that a 20% discount (or was it 10%?) was a benefit of being a MBOC member. I took full advantage of this as recently as 10 years ago. However, between then and now, we've had all of our service work done by our friendly local independent, so have had no need of it.

The MBZ dealer close to home practically threw me out for asking for the same discount a few weeks ago, since I've again started doing some of my own repairs, so I guess it doesn't fly anymore.
