Crutchfield's catalog usually has a chart of car receiver's specs,
including sensitivity, which is usually how I base my choice.

  My current receiver is a Dual with a built in HD tuner, which I'm
pleased with, 'cos now I get more choices on my local dial.  I can
listen to all the time NPR talk on our classical music's HD3 or roots
rock without commercials on a rock station's alternative channel.

   Disadvantage? The side channels are the first ones to go bye bye on
a trip out of town.  No picket fencing like conventional FM, but lost,
found, repeat, change station.
