請問：我還能砍多少

這時某dealer 發給我的 price quote：
2012 Nissan Altima 2.5 S in Super Black or Brilliant Silver are equipped with Carpeted Floor & Trunk Mats and Splash Guards. They have a MSRP of  $23,650. The SPECIAL INTERNET PRICE is ONLY $20,625* plus tax, title and license!!! 

*Quoted price includes $1,250 in rebates ($750 + $500).

Special financing of 0% for up to 36 months, 1.9% for 48 or 60 months, 2.9% for 72  months is available in lieu of $750 factory rebate for all Altima sedan purchasers who qualify with approved credit. If you are a recent college grad (within the last 2 years or in the next 6 months) there is another $500 rebate available.

我2010年畢業，還能拿到那個500的bonus, 減去這500， 是20125， plus TTL.

請問我還能照這個價砍多少？
