I bought this motor from a dear friend. However, this motor is being sold in the market starting from around 80-150k depending on the variant as it came as an Auto version producing 180hp and the manual one producing 200hp with an upgrade of type S/Euro R cams, bigger throttle. Besides the variants, the market location, condition of the motor, included accessories, condition of the wiring, sensors and the transmission you're getting is also a factor of the price tag. Further its your own bargaining power.
P.S mine is a manual version with a different transmission from an F18 SOHC.
