I like silver, I just traded my Argento Nurburgring Cali T HS for a white 488 spider. Before that I had a Rhodium Silver 991tts and a silver Bmw X5. If I had found a spec in silver I liked then I would have bought it. The thing is, there are plenty of buyers at the right price for all the cars. Color only helps make the sale but I don't think it will keep the car from being sold nor will it cost the owner any loss in value.
