My guess.......it's a mnsubaru member that has a grandiose perception of what subarus and subaru parts are actually worth.
All new bolts, cleanest in the state, rare and sought after color, and partially disassembled block with forged pistons which may or may not be installed depending on how you interpret their vague description.
^ You forgot about the ashtray full of "clean'' dollah bills...some of the most clean you've ever seen! At that price it may be the glovebox...or trunk?
Didn't you know that increases the value of the motor 10 fold... This way you can see what you are getting
Better bring your tuner with you so it can be properly tuned before you drive this one off the lot ... That would be one expensive failure.
