I once went to an auto parts store and asked for a starter for a Cleveland. The parts guy said he couldn't look it up unless he knew what car it was for. I told him it was for a Pantera, and he couldn't find a Pantera, so he went to his boss who told him which starter to get. He came back with the correct starter and told me that it cost something like $486. When I asked him why it was so much, he said parts for exotic cars cost more. I then asked him to get me a starter for my 'other' car, a '72 Mustang with a Cleveland, he came back with the same starter, which cost around $40 (or thereabouts). His boss had no explanation why the same exact starter, with the same part number cost 2 hugely different prices.
This is a slightly different example, but the concept is the same.
