Trade value on 2007 CTS 3.6L
 

What do you guys think is a fair trade-in value on a 2007 CTS 3.6L with 32k mileage? Its very clean.

NADA says $21,600
Edmunds = $21,200
KBB = $18,500

Retail Value:
NADA = $25,125
Edmunds = Dealer = $24 - $25k, Private Party = $22 to 23k
KBB = $21,100

Local dealer is selling similar cars for $23 to 24k. Had a dealer try to offer me $15k on a trade.
