I ordered mine 8 months ago so I am not sure what the current prices are or how they have changed. I heard somewhere that the price was dropped by $1500 or so. However, I got about a 10% discount at the time which I thought was OK considering the car had just come on the market.
Your price sounds good to me, but I am not sure about what the options cost now (eg. M-Sport wasn't available at the time). As a general rule, I always aim for 10-15% off RRP. If you are a really good negotiator and you catch the dealer at the right time maybe a little more.
There may be others here that could give you a bit more feedback on the current prices. There is another discussion here
