I would absolutely buy a Porsche as a daily driver. Just make sure that you get it up to good operating temperature every couple weeks. Not to discount this idea, but if the Porsche is a bit much, test drive a VW GTI. A thousand times more fun and engaging than the crossovers you mentioned and practical as well. But a Porsche should be able to handle daily driving tasks with ease. And I’d have no qualms about drivability in winter as long as you get proper tires and wheels. I’d be way more worried about rust.
