Wow! What a find!
I'm a sucker for the green cars, and that's quite a story to go with it, too! I'm glad to hear it's holding air, and it sounds like it's basically a time capsule. I'm looking forward to the pictures.
As for your image posting troubles, I know that one of the perks of becoming a paid member of the club is unlimited disk space for attachments. Without that, I know that not a lot is provided, particularly for "modern" photos of cars.
You may be able to host the image elsewhere though, and post a link.
