Am currently seriously tempted by a W plate 7 seat Disco TD5 XS which has been taken as a trade in at the moment. No rust, straight undented panels (bar one front bumper corner scrape) dealer service history upto around 20k miles ago, low miles (relatively) and a heap of toys and goodies from new including heated front screen, heated leather, upgraded sound system etc etc and on a par with Omega Elite spec. Buy-in price is 'fair' but a team member buy also suffers from corporate greed and will probably attract a premium price given the time of year and the weather 'demand'.
On the opposite side of the coin, my old 300tdi commercial is bashed and scratched to buggery, two seats, barely working heater, is a skip inside but has had the major bits fixed such as wheel bearings, new discs and pads, timing kit, and the rusty bits that fall off have been welded back on. And its due me nowt, cashwise.
I would still get about half the purchase price for my old commercial against the purchase of the new one but its that old eternal question/challenge.
Better the devil you know and all that....
