Thinking to change cars, whats mine worth

[limoncello]

im thinking of changing cars, maybe a d4, not sure yet, but any ideas on what mines worth

2005 D3 dual grill model 3.0 TDI, 150K miles
black - with grey (or platinum as they call it) interior

Been fantastic really, never failed to start, hybrid tv, MMI2G, AMI music with hard drive lead and lead for ipod, hard disk drive 320gb. bluetooth phone module not working and i have removed it and put a loop in place. just need to get a new module from ebay and plug it in. elec boot all working perfectly,

mot till july , no reason it would fail the next.

new tyres 5 months ago, alloys not great, scratches etc

dvd / usb / sdcard player in boot, headrest monitors in the rear, all works from the front with a remote. (on AV1) you can also put the tv through in to the rear

needs a good valet thats for sure, but anyone any ideas what its worth

engine light is on, but its only the MAF sensor , i have it booked i to Audi leeds to get that fixed.

havent got any pics at the moment other than the one in my sig
