It's funny how many people ignored the fact that SR+ is RWD and of course, they would claim to be "fine" in winter. I have had 3 RWD cars in my garage as of 2 months ago (2 sports and 1 EV, all with xice3), none of them will be able to get me out of trouble if a snow storm hits. I even had issues just getting up a very mild ramp in a parking lot.
The discussion should be two part - RWD vs AWD and the price.
First of all, I would never spend $50k+ on a RWD daily car in Canada. It's all great until the day that you get stuck. The slip start helps, the weight of the battery pack helps, experience can also help, but physics is physics. My experience tells me that all you need is one occasion that you need that 4 wheels to put power down to get out of trouble, the extra cost would be justified. There has been way too many hairy moments with my RWD cars in winter that I don't think it's worth it if it's your daily car. Weekender or fun car is a totally different story though, apply that to your situation. Seeing that you are in Vancouver, this may also not impact you as much as us in Toronto. The other piece is also the acceleration on the AWD is noticeably quicker, the premium sound is enjoyable, the rear heated seats are nice (although upgradable).
Second part of it, with 55k is quite a lot of km for a relatively new car, I'd stay away from it regardless of warranty. It's a decent amount of savings given Tesla's resell value, but it also isn't enough for me to take on a car with this mileage when it's only a year or two old. However this is a personal preference and your experience with used cars, some people might feel comfortable with it.
For reference, I still have my RWD cars as fun cars, with a LR AWD as my daily commuter.
5th winter with my rwd model S..... With snow tires it is a beast in winter.
