Infiniti offers 16k for my 06 G35

Should I take the bait? Since no one HS kids can afford to pay asking price for my G35 Coupe. 16k is a bit low. KBB for the car is about 22k. (The ricer scene basically destroyed the resale value of this car.) No one wants to pay more than 12k for a  mint G35.

Is there a catch?  Do I have to use the money to buy another POS Infiniti vehicle?

I'm looking to purchase a 2011 Lexus GS instead.
