I have a silver hardtop for sale that was originally fitted to my wife's previous Z3 which was Arctic silver. I always believed this to be the colour, but after fitting it to my son's Titan Silver car I am not entirely sure.. I have a photo below of each car. Arctic Silver Titan Silver. If Arctic has a slightly bluish tinge then that is the difference and colour, but to be honest looked absolutely fine on the Titan car. The hardtop is in excellent condition bar a few light swirls, but no scratches chips or dents. It comes with the genuine BMW storage bag that means the hardtop can be suspended from the roof of a garage or shed. The Z we have now is Sterling Grey and I kept the hardtop, as the buyer of the old car had no requirement for it. I also have the genuine BMW fitting kit on another thread. I am after £650 for the hardtop and cover (collected from Telford.) Though if not too far away it could be delivered if costs were covered.
