How much should a 2005 cummins (325hp/610) with 70k miles in excellent condition complete with all wiring/ecu/fuse box, etc. fetch?

I have a extra from a project that will never happen, thinking about selling it.

 

$5k + shipping reasonable? 4k, 3k, 2k, 1k?

 

$7000 new from Cummins. I'd say $3000 would be reasonable.

 

cool... I will keep looking around online, last common rail (04.5) I seen with 75k sold for $4500 + shipping online. You don't see too many for sale though.
