Hello mate,
I just sold a K reg 3.9 top of the range SEi with full leather etc. etc. on Ebay.
I got £430 for it.
it was in great condition but needed some welding on the rear Xmember.
If it's got to go I'd not bother putting a reserve on it,
You just got to let it go for the current market value,
As RRB says, it's not going to be a lot.
Scrap value is about £200.
If you want more and you have the time and the space then break it.
you might get a couple of hundred for the wheels and tyres if they're decent,
the axles will get you £50 each.
Engine and gear box should fetch around a ton if they are O.K.
Body panels, roof, roof lining and tail gates will sell easy if they are in good nick,
depending on the condition of the interior you should get a few quid for that especially if it's leather.
Cheers,
