A few weeks ago did a track day at Buttonwillow, and then drove to Pismo Beach to play on the beach/in the dunes. I was pleasantly surprised at the car's performance, both on asphalt and off road. It's truly a capable car in both environments.
I was the only crossover (let alone Infiniti) at this particular event, but it was definitely not the slowest.

I didn't get stuck once, but the key was keeping the momentum going. I'm sure if I had different tires, it would have been even more fun.
