Dusty Old Cars and gave me pocket change in return. Nashua New Hampshire

I advertised my 1974 Pontiac for sale on Craigslist in November 2015. About two weeks after, I received a phone call from Dusty Old Cars. The salesman asked if I would be interested in putting my car on consignment with them. I told I would be interested. We made an appointment to meet at my address so he could evaluate my car. We met and he looked the car over and he approved the vehicle. He told me Dusty Old Cars usually towed each vehicle to their warehouse, and I would not be charged for the towing. The towing would be added to the sale price of the vehicle and passed on to the purchaser  when the car was sold. Also any repairs to the car would be added to the sales price. My Pontiac was running and could be driven. This car passed inspection every year that it was registered. It did not need any repairs. The body had no dents, no rust. The car was straight as an arrow. All the glass was good.  Dusty Old Cars did not even respond to my several e-mails I sent asking about the status of my vehicle.

      I have a signed contract guaranteeing me $3700 after the sale of my car. Dusty Old Cars had my Pontiac listed on their site for over $6000. All said and done Dusty Old Cars sold my car, charged me  the towing fee of $200, charged the repairs to me and sent me a check for $217.  Why would I spend 3 or 4 thousand dollars for a return of $217.00?? Totally absurd.
