You should be able to post more than 2 pictures. Here is a topic on how to post pictures to this site: https://cccforum.discoursehosting.net/t/howto-post-images-in-the-forum/86/1
The more pictures you have and the better your description is of your Cougar is the best way to sell it. Questions that you might want to answer in your topic will help also. Here are a few.
- Any rust issues?
- Cowl leaks?
- Body repairs or filler?
- Modifications
Pictures up close from multiple angles help. Pictures from the underside of the car showing floor boards, door bottoms, torque boxes, steering components, suspension, brakes and exhaust.
I hope this helps you. Good luck with your sale.
