"...make me an offer..."

So my friend said down the pub.
He'll be selling his series two Disco (Auto, 02 reg, 70k+ miles, leather seats, etc) after Christmas and he's asked me to make him an offer, a few scrapes n' scratches but otherwise in great nick. On the same note if I buy it it'll mean me getting rid of my series 1 Disco, (Man, 98 reg, 90k+ miles, cream leather seats, 50 year anniverary version). How much can I get for mine and what should I offer for his. Any ideas?

Cheers
Alex

Diesel in both cases.

Have a look on Auto traders website and see what both years are selling for, that will give you a good indication.
