triangles and plastic covers
Nope. They are not included in Canada either. Here are the facts from my research:
Triangles: in some places, warning triangles are required, by law, for all vehicles. In order to handle this, most European cars have space to store them cleanly. Here, in Canada, only commercial vehicles require some form of emergency warning (either triangle or flare). In an effort to keep costs down, cars shipped to areas that don't require triangles still have the space for it but don't have the triangle. You CAN order the triangles from your local dealer for a small fee. I think I paid 20 bucks for mine.
Plastic Covers: VW was worried, back when they first released the car, that the top may have issues closing even though their extensive testing showed they were very reliable. Because of this, they included these inexpensive "one use only" covers to keep the cars dry in case of a top failure. Since then, months of deliveries and no top issues confirmed that the top was reliable enough not to worry about mass failures. They discontinued the covers and we can't even purchase them via the dealership as an after-sales part. The covers don't exist in the ordering system anymore. I have heard that some dealerships have some, and you can probably get them from EBay... but I don't think it is really worth it.
Basically, the cover is a one use thing designed for a top-moving emergency. They are evil to put in, and take longer than putting up the top normally (so no reason to use them as a "quick cover" instead).
I did buy a VW triangle because I am a safety-crazed lunatic that has tools, blankets, first aid kits, air compressors and various other "things" in the boot for emergencies. A triangle that fits the little slot just seemed natural to me.
I looked for the cover and found them available for FAR too much on ebay and decided that I'd rather have warranty cover "blow drying the carpets" than pay over a hundred bucks for a one-use plastic cover that will probably take too long to install during a flash rain to help anyway.
Your mileage may vary... Maybe a local dealer has a hidden stash of the covers. None in Canada did, because not many were delivered here before VW decided it was a waste of space/money.
Cheers.
Sarcastic note: if you really really really want to have a cover for your car for that time the roof won't close when it is about to rain... I have an answer. Go to your local camping supply store and ask for a rain jacket for your heavy-set friend. Tell them you need one in an XXXXXXXXXXXXXXXXXXXXXXXL size. That should work. And, when not in use for this, you can tie off the arms, use the air compressor (I mentioned I have one in the car, right?) to blow it up and use it as a play pen for the kids!
I'm all about multi-purpose objects!
