I'm thinking about selling my WRX wagon what is it worth?

Stats:

ONLY 5600 miles
2004 Silver WRX Wagon
Manual Tranny
Security System Option
Alpine CDA 9813 cd/mp3 player ($399 + install)
Boston Accoustic FS60 6.5" components ($250 + install)

Thanks!

 

I did, it says its worth $22,800. Do you guys think I can get that for it? I was going to offer it at $22,000. Any takers? She is in perfect shape
