Here is a link to a 71 GTO I sold on consignment recently. The owner had it on craigslist for 2 months at 12,500. He had very average pics. I took a whole group of pics and sold it for $15,000 in 2 weeks off of craigslist. The pictures do make a difference.

Your car does seem to be a great deal. Just get some good evening shots.
