Is this Duster overpriced?

Talked to the
H code refers to a "340" Duster. The vin would read VS29H2..V for Valiant, S for special, 29 is 2dr coupe, H is for 340V8 and 2 for 1972.

Pics of the VIN and options codes plate are supposedly on their way to me. (I will share those photos on here, if I do receive them). I let him know that the car was listed at $5K over average retail- no response from him. Dealer bought the car in upstate NY in the summer and drove it back to FL. He doesn't know for sure if it's matching numbers, believes that the mileage is accurate at 91K, doesn't know if the drivetrain is original to the car. The car is in storage and it sounds like he is not in a big hurry to sell it. More updates to come.
