08 BMW E90? Deal or No Deal.

[bape_sta206]

I'm in the mist of purchasing a 08 E90 with about 10,800 miles with the following options: Jerez Black, Black Leather, carbon fiber trim, manual, premium package, cold package, tech package, 19", moonroof, clear bra, and Ipod connector. Listing price is $49,000. Dealer is willing to give me 2000 off the asking price. Should I pull the trigger or bargain more? Should I purchase an extended warranty? What should I check before making this purchase? Thanks
