Any specific reason for high end? As in, are they looking for badge presence or gadgetry?
I'll throw an option into the mix, and hear me out:
Toyota Land Cruiser
Starting at $85000USD, it slots right in with the price range being looked at. If purchased outright and not leased, the resale values are still exceptionally high. It still has pretty much all the tech that you'll need on the road (except some silly gimmicks that you'll use once and then forget about), and it will be far more reliable than any of the other options.
Also, those off-road and towing capabilities... Perfect for Island living when storms hit.
No, it's not flashy, but it's still very much a product for people who want to buy something that's high quality, highly reliable, retains resale value, and will still blend in with the plebes when one is forced to go into town.
The only downside is that because it's not officially sold in Canada, it has to be imported via the grey market (though I've been told by the Toyota dealership my parents bought both their cars from that they can special order it into Canada without issue.)
