New (used) A4

["Ben Lee" <benl@intrinsix.com>]

Got a new (to me) A4 last week.  So far I love it.  But I'd like to get it
checked out, and the local dealer is booked until mid July.  Does anyone
know of a good Audi mechanic in the central Massachusetts area?  Something
close to either Westboro or Lowell MA?

Also, when coming to a stop at slow speeds I hear a low grinding noise from
the left rear brakes.  I've noticed alot of brake dust on the rims on all
four tires, but that one has alot more.  Any ideas?  The dealer put on new
pads right before I took deliver of the car, after the test drive.  The
noise wasn't there during the test drive.
