Motion Corvette Info

[starrider]

Unfortunately life has taken an unexpected turn so I am looking to sell off some of my things. I am trying to get a ballpark figure on the value of one of my cars. I have a 76 motion phase 3 L88 Vette that I purchased a while back and stored away. It has solid documentation from both the dealership and Motion Performance which includes a Motion receipt that lists all options and a letter from Mr. Rosen that states what it is and being capable of running 10 seconds in a 1/4 mile. I am hesitate to post pics at this time because of the possibility of scammers trying to duplicate the documents. It appears the car has the original engine , trans and rearend except the gearing have been changed. The body and interior are very nice but the paint is not the best. I am hoping to get some advice on the value and what might be the best way to sell it. Thank you in advance.
