From 2014 it'll still have 2 years left on the drivetrain warranty (battery, drive unit) which are the big-ticket items if they have to be replaced. You'd want to budget a couple grand for eventual replacement of the center screen, and be aware that repairs can be expensive (like any premium/luxury brand). From 2014 you might want to check if it has free Supercharging, I don't remember when that became standard. Also think about where the nearest store/service center is, or check with Vancouver about Ranger service. If you need tires/brake pads etc. you can get those done at most tire shops now, but some stuff you'll still need Tesla to service. Living in Edmonton means taking my car to Calgary every now and then, once every couple of years, so you'll probably have the same requirement to go to Vancouver once in a while.
You probably won't find anything at $30k that's more fun to drive though.
