If it's your posting you might consider putting more photos on a place like Photobucket, Imgur or Shutterfly. (After a wash/wax/vacuum, it's not hard to take 50 or a hundred photos of the car... you'll be much more likely to attract higher price offers. Everything from the tire tread to the VIN label should be photographed, if you're seriously looking to get $20,000 for this vehicle.)
The price is more than I'm looking to spend right now, but this is a potentially nice find for somebody. Good luck with the sale.
