Potential 2007 4.8 purchase - but what's the catch?

[jeremym]

Here are the specs:

2007 (08/2007) 4.8i CPO
39,077 miles
Tech package
Sport package
Premium package
Cold Weather package
Panoramic sunroof
Almost mint condition, according to online photos
No accidents or any negatives (per carfax), 2 owners (1 lease, 1 personal)

Dealer is asking $35,999. KBB CPO value is at $44,500. All the other 2007/2008 4.8's the dealer has are over $40k.

There has to be a catch here. Carfax says it's been on the market at the dealer since October, 2010. If there is no catch, what are the odds I can talk them down to $32-$33k? I have financing secured already so I just need to walk in and write out the check.

Any input is greatly appreciated.
