Never mind the novelty of it, it's a bigger space inside, so instead of being limited to 4 or 6 of your friends (plus you as the driver), you can have 8+ people in a limo, plus (by the time gen AA or AB is ready for it) a robot for driver. The glory days will be back as soon as self-driving cars come around and people come to appreciate all the extra interior space, and are able to afford such a luxury.
