This rumor has been out since long. I was offered a silver one as on-the-spot delivery at 50K premium only, at the time this version was released, back in early June. I passed the offer for 2 reasons, yet mainly because this discontinuation rumor was out, second reason being that I wanted a black, so hence, I booked one and got it delivered in August.
Now this rumor is out again, and I cannot believe so many showrooms reporting wrong......... time will prove. The color by itself is excellent, I do not understand why they'd discontinue it, perhaps deeming that 1 shade in silver is enough, the medium silver.
Those showrooms that have one in stock course cannot confirm such changes to be made.
I'd say, if you like the color, and can get a reduced premium offer, hence 50%, there may be some weight towards taking it. If it's absolutely "no, no" to silver, or they demand full premium, better pass on it.
