Is this a fair price for 2015 Altima?
 

Dealers tell me they have a promotion for the Altima 2015. They provide me an offer: $23495 for 2015 Altima 3.5S(3800 dollars off MSRP). I haven't purchased a new car for ten years and not familiar with the current market. I compared this price with some deals shared in autopriceshare.com and it seems fair. However, there is no incentives or rebates associated with those deals.
Could someone here give me some suggestions about this deal? If you know some useful incentives or rebates related with Altima, please share them with me. Thanks in advance.
