Not sure how rare it is but my dealer had one. I think it was a '13 or maybe '14 and I think it was an Exec. They had it on the showroom floor for a while. The sales guys kind of joked about the color but at the end of the day they know there's a buyer for every car, and someone did buy it. A wealthy retired farmer.Is the toffee brown metallic color the rarest of the T3's?
