It's going to be dependent on the area but that sounds about right. The sales person was correct in that these cars are in high demand with a low supply.
I don't know what the differences are between 2012 and 2013 but I got my '12 premium for about $27.5K on the east coast. Add those options you got and the price is close to what you will be paying. I personally would have gotten the roof rack myself later and installed it as they're probably charging you for labor on that.
