I owned a Mustang convertible
I owned a Mustang convertible and later a Corvette convertible, and both were my daily drivers. Both were really fun to drive. But I would have to add that cars like the Porsche 911 and Corvette are more expensive, and owners are more likely to have other commuter cars at home to slog around in the daily traffic grind. Also I'd say that the daily driver use year-round depends a lot on where you live. In sunny California, I didn't put my garage-kept Mustang convertible's top up for 10 months out of the year. But it would be a different story if I lived in Minnesota.
