Great VIN tag. The car is definitely rare (HO, air, disc brakes, PW etc). Worth more than just a 400 car with webbed feet... lol
It lost it's front end at least once, floors gone, paint covering up everything else.
If the engine matches the VIN then it's worth something but I would assume the body is not worth much.
You need to look at it up close. Hard to say if it's worth $9k or not.
