Extremely responsive car with Good fuel economy. Driving assist system is extremely helpful as well. The audio is somewhat lacking (speakers) but NOT a deterrent to the car at all.

The car is beautiful, but I couldn’t buy it because it was making noises when I drove it. I can’t buy a car that I need to bring to the shop as soon as I get it.
