Mainly the lack of a manual transmission. The interior options seemed too exotic for me. The RCA line-in jack is possibly the stupest implementation of a line-in I have ever seen on a car.
Mainly issues with my inexperience with the paddle-shift, the car just didnt feel right. We went thru a short twisty road and I found myself being way too cautious on account of the way this thing (or I) was shifting.
