Ned...
If it helps at all I have a 180 I am breaking, the KV6 engine is pretty much all there still (needs the manifold screwing back down and a cam \ crank sensor installed) 85k miles and was in perfect condition when I parked the car up
I can do you a good deal on the engine if your interested?
Personally I would be asking for my money back from the trader and looking elsewhere for a new engine
