Congrats!
Assuming this is a '14? If it's a '13 you might want to rethink the deal before signing papers, a quick check of the local dealer inventory here shows advertised prices on the website (before even having to haggle) as up to $4900 off a '13 SEL (probably more markup on a Titanium since it's a higher trim) and they have a 2014 Titaniums listed for over $4k off and $3600 off on '14 SEs. Being these are advertised prices, there is still room to go down from there.
If it's a '14, I think that's a decent deal. If it's a '13, I would rethink.
