Henry's may still be open. His wife was an active
participant in alt.auto.mercedes, handing out lots
of good advice. I *think* she said the shop was staying
open, but has since disappeared from that forum.

In North Dallas, I hear lots of praise for Rodney
Herson, located on Davenport. I've no direct experience -
none of my out-of-warranty MBs has ever needed a
repair significant enough that I needed to have it done.
I did purchase a car which was exclusively maintained
there, and it was very well cared for.
