is a blown engine 5speed X5 worth anything?

[Phr3d]

~140k mi, presently located at DM BMW in Iowa.
I will need to play wheel swap as no one seemed to care much for my choice of wheels, it will be left with my 57's (winter wheels) and Pirelli Zero's with approx 4k tread remaining.
all else stays (4.8i exhaust, DEPO front/rear lights, ipod connection) as well as a brand new clutch, most door and window mechs replaced in last two years, all new shifter bearings etc,calipers cleaned/painted black)

Vehicle has an unfortunate scratch down the side that we don't know when/how it occurred, seems to be a white plastic material that might buff out, no metal damage. One scuff on black plastic up front. Entire front was cleaned up, buffed out and repainted 2011 when headlights were installed, looks new/good excepting scuff. Non-sport Interior very good, but has had smokers.

some pics in album albeit without the pictured wheels. more here:

All service performed/recorded at DM BMW, approx $8k. They inspected the drive-line today and stated that it -was- worth popping in a BMW-remanufactured heart, we have not completely decided that we are unwilling to pay the $7500 plus labor to do so. (used engine is cheaper, of course).

Ebay presently has a sport version of this selling at $9k-reserve not met, so I guess I will see if/where the offers fall.
