I got my '15 PCX new in early 16 for around $3000 (if I remember correctly) + extra to build it and shipping fee. I think the build fee was like $100-$200 and another $100 for "shipping" it to the dealer. I think your getting an average deal.
Make sure the helmet you get is Snell certified. From what I remember the Snell cert is higher than the DOT cert. If this is your first helmet and you don't know what your doing, have the dealer fit you for a helmet. Its very important that it fits properly or it wont be as effective in an accident. When I got my PCX I got an HJC helmet from the dealer since I had no idea how to size one correctly. They are very nice helmets.
As far as bluetooth, make sure you read local laws. Some places make it illegal to use headphones while riding. Also, if your a new rider I would suggest not using them for a while and concentrate on the road.
