When is it not "Original" ?

[MadMike]

I'd say it's original.

Come on. If you kick up some tar on the road and get the underside of your car dirty - and you wash it - is it still original? You mighta washed some of the undercoating off!!!!! or even some inspection marks or identification tags (shock/horrors).

If the brakes wear out - you replace the pads. Is it original? Restored? Fixed? Ruined? Maintained?

So someone sprayed paint all over the inside of the engine bay. It's original and it's "messed up". So what. If you want, you can fix it. It's still original.

If you rebuild the engine or repaint the car, it's restored. IMO.
