Why don't the CSS tabs show?

Hi everyone

I’m going a bit crazy here – on this page I have three tabs with information about my car.

The CSS is set to display the “More” tab first. But clicking the Interior and the Exterior tabs won’t bring up the text in their divs. The page does validate, btw.

Oddly, it used to work but suddenly stopped. It’s really weird because to me the CSS and the code in the WP page look fine.

Can anyone put “fresh eyes” on this because I’ve gone blind? Thanks in advance for your help.
