Is it worth it to upgrade to a Ford Focus ST?

I currently own a Ford Focus and I'm thinking about upgrading to the sports-tuned ST model. Is it worth the extra cost and what are the main differences between the two?

As someone who has owned both the regular Ford Focus and the ST model, I can tell you that the upgrade is definitely worth it.

I would say it depends on your priorities. If you prioritize performance and a sporty driving experience, then the ST is definitely worth it.
