Matt, all

In Europe, Harley Davidsson motorcycles have had an enormous success! This
from a rather limited sale.

One of the strongest arguments is that you can fall in love with it and have
it a lifetime, as Harley guarantees full service and a lifetime stock of
spare parts.

The mistake they have done, and is severely suffering from, is the
introduction of an electronic ignition system. All of a sudden the motor
won't run, and even if you are an excellent mechanic, there is nothing you
can do. To keep it's good reputation, Harley guarantees to pick you and your
cycle up anywhere, even in the middle of the night. I don't know if this
guarantee actually works, but it shows what efforts a manufacturer has to do
nowadays, to save it's reputation.

This has nothing to do with wildlife recording, but reflects the same kind
of thoughts which are just now discussed in this group.

Klas.
