I can see the discussion regarding the Jaguar owned by Mike John as above could quickly escalate, and get out of control, so I'm going to say right now I don't want any further discussion posted on The Roaring Season about the originality of this car.

Race cars, by their very nature, in order to remain competitive, evolve. They suffer accident damage, and later in life, when they're no longer competitive and their values plummet, they often suffer neglect. So its extremely rare any old race car remains completely intact, retaining every piece it was fitted with in period. The amount of originality a car retains varies from car to car, and every person has their own opinion on what makes a car original, or otherwise. There is probably no right or wrong answer, just different opinions, and by arguing the fact on here will achieve nothing other than cause argument for the sake of causing argument. And at the end of it all, nothing will be achieved other than everyone disagreeing.
