In the late '70s and early '80s I would occasionally to go a local dealer to buy a part, and the parts guy would condescendingly tell me that my '72 H2 was too old, and parts were no longer available. That attitude caused me to make the parts I needed whenever possible, and avoid dealers as much as possible. Nothing any car or motorcycle dealer has ever done since then has convinced me to change my attitude, although I've seen plenty of stuff that reinforces it.
