you must also take into consideration that when people do these engine swaps they also generally do a whole lot more than the engine, the cars that are selling for $10k and over generally have been resprayed and the bodies are in very good condition.

My ute is an A series and everything is as if it just rolled out the factory and I love watching all these other cars go for so much because it know that it drags the price up of mine... There was also another little white ute that surfaced a few days ago (in a thread on here) and its a beautiful mostly original example, I would think it would be worth quite a bit.
