I've just been reading through this post and I think it's a great idea.

I have been keeping the banner fresh lol

I'm happy to change the banner and have peoples cars in there. It just needs to have the following:

1. Same Dimensions
2. Standard text "All the information on the Fiesta ST"
3. The image must stay on theme or be informative. No offensive/disrespectful images or text.

A theme like this would be great. I'm sure it would be monitored without bias.
