You're quite right - there doesn't actually to seem to be much about for some reason right now!
Other than the £30k+ RHD one, the only 4 I know about are:
viewtopic.php?f=56&t=708 - Vin 3078 at £20k
viewtopic.php?f=56&t=136 - Vin 11761 at £18k. This is the one you've mentioned - an ex-middle eastern car, and has been for sale for at least 1 year, in Antrim, Northern Ireland. No-one seems to know much about it, but there is a topic on the Ireland forum:
http://www.delorean.ie/forum/viewtopic.php?f=2&t=1197 - there may be someone in Ireland who can help you, or ask
Matt, who lives in Antrim and might know someone who knowns someone!
John Geuley has a car for sale apparently - but again not totally sure on the details, other than the price is £15,500 and it's in England
And
John Dore in Ireland is selling his
black car, which "needs work", including a frame-off. No price as yet, he's "open to offers"
Other than that
Chris Nicholson offers a purchase/import and restoration service for a price. If you have trouble contacting him here then mention it here - there are a few of us who have ways of contacting him!
And I'm fairly sure
Martin would offer a purchase/importing/restoration service for a price too! Of all the links mentioned so far Martin is the one who will reply the quickest!
Also
Ed Uding will have one for sale (in The Netherlands).
Other than that you'd need to look at ebay USA and importing, which isn't all that difficult. There are a few people here who have done it and say it's fairly easy - I can point you in the right direction. Remember you'll need to pay to get the car to a port, pay shipping (£1300+VAT), then pay VAT on the price of the car too.
