That kit price was insane.

I paid less than $100 total earlier this year for a E24 and F52 Enerjet motors in a combo deal.
While not in bags or boxes, they are pristine and in unfired condtion.
That bozo will never get an offer at his starting point on those engines let alone his buy-it-now price. The ones I have seen in the display box packaging have went for less than his starting bid of the bagged engines.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
