Collectability is in the eyes of the beholder. If you are looking to sell in the future then this upgrade could swing either way depending on whether the future buyer wants stock standard. For me this is not an issue, Vader is a keeper. It is whether this package completes the vehicle or merely adds to it. This is what I am wrestling with at the moment. After watching the video I love the factory look. However the XR8 would have to be braked better. Black 6/4 Brembo's would be a great finish to the car. But then you are looking at almost $30k investment. Is it worth it for a "Falcon" which is not a Sprint or GTF?
