what's my Multivan worth?

Hi guys and girls,

I have to sell my 2005 Highline Multivan, but have no idea what to ask for it.
It's only done 115,000kms. Its a manual 2.5l AXE diesel 4 Motion.
Has a few minor body scrapes, but is otherwise in good nick.
Has factory tow bar and roof racks. Aftermarket Kenwood Sat Nav with Bluetooth and a Miro installed remap.
I didn't find anything comparable on Car Sales or Drive, so I'm asking for thoughts from the forum.
Cheers,
Rod

I'd take a stab and say around $15K.

I know it's very general but it might help as a indicator to begin with if there are current listings to compare
Used Car Research - Used Car Prices - Compare Cars - RedBook.com.au

Thanks Gold Coastef. Just what I wss looking for.
