Thanks tekbis. When I was ready to pull the trigger back in September I had originally planned to get a GT in Machine Grey, (the only color I wanted) but no dealer had them in stock and I would have had to factory order, and wait for 2-3 months. Also, since I had a trade-in, the factory order would have complicated the deal - the dealer could have re-assessed the value of my trade when they got the car in (although of course they said they would not). The only models that dealers actually have in stock here in the GVRD are the base GS and the Signatures - the GS-L's and the GT's fly off the lots. So I decided to splurge and get a Signature in machine grey in early October, even though I didn't really need all the extra features and wasn't enamored with the "chroma brown" leather as they describe it here in Canada. But I am glad I did get the Signature; the chroma brown colour has grown on me and I enjoy the little extras such as the ambient lighting around the console; the interior just looks more lively and rich than it would with just black leather/black trim. Sure I might have gotten a better deal at year end for the Signature but I was happy enough with the modest discount plus the decent trade-in value that I received. The funny thing is that I have not seen any CX-9's whatsoever here in my neck of the woods. Of course the allocation to dealers here is much less than in the US (one dealer claimed that he got 2 CX9's every three months), but I would have expected at least one to cross my path by now.
Congrats on your purchase - you will love driving this vehicle. I suspected that Mazda wasn't going to add much in the way of features to the '17 model. I don't care about a panoramic roof, or ventilated seats which seem to be major complaints about the car. The only features that I wish it had are power-folding mirrors so I could park the car more easily into my garage, plus a 360 degree camera, again for ease of parking. IMHO these are way more valuable features for a big 3-row crossover to have. The only thing I would be concerned about with the '17 is the V59 software which your car may come with pre-loaded, depending on when it was built. From reading the other threads in this forum posted by 2016 owners who have had the V59 update, the V59 has certain bugs making the owners regret that they updated.
