This has just reappeared on eBay again with another £4k price drop.
It also has a spec list now, although it seems to have a couple of errors in it (T3 intercooler and Teflon cam belt)!

It could be a decent base for a project for someone if it drops again!
I wouldn't imagine it would take much to get the front end back to looking stock.
However, the rear end might be a bit more work depending on how badly the arches have been cut back.
If they are cut back too far for a set of ZGs, another option could be ZTrix Subtle Z rear arches:

........... and another set of wheels!
