I deal in classic cars for a living. I see this all the time. People ask "what is it worth" and get prices all over the place. When it all comes down to it what would someone REALISTICALLY buy the truck for? Anyone can tell you $35,000-50,000 for the truck but would they ACTUALLY pay that if they were really buying it? No. Plain and simple, If they aren't willing to cut a check on the spot for the amount they are quoting you, that's not the price it will sell for. An appraised value is not a market value. It's an insurance replacement number considering the time money and effort it took to restore the truck. Actual market value is what someone will pay for it. Your truck looks to be well done with good service and restoration history. That is worth a little more than a truck that was bought at auction without knowing much about. When I had seen the pictures the price that came to mind was $26,500. An odd number I know but that was my gut feeling. Asking price of $29,900 gives some room for negotiations. Now my personal opinion is different than my professional. KEEP THE TRUCK! I think your Mack will bring you more business in return as a form of advertisement then the cash you will get in hand from the sale. I found my diesel mechanic simply by having a business card his father handed me two years ago with a picture of a B61 on it. I have since recommended him to several other guys and he has gained business from word of mouth. When people see your truck at a show with a sign in front that says "restored by..." They will take a business card and flyer. Think of all the business Pfahls gets from showing his trucks? Plus the truck has now become a business write off and all the shows and events you attend with it now become business expenses. Fuel, hotel rooms, meals, tolls, etc are now expenses. Ultimately you will know which decision is right for you.
