It wont be more than £30k in my opinion!

The Mustang Ecoboost is £28995. And the Mustang GT is £32995. So they will market FRS between them to not damage sales on both the Focus and the Mustang. If its less than a Mustang Ecoboost, then that entry level Mustang becomes useless. Dearer than a Mustang GT, who in their right mind would by a Focus over a V8 Mustang that was cheaper.

Interesting to see what's the craic with Mountune or if Ford Performance themselves, offer warranted modifications from the dealers. I know Mountune currently have a white Mustang Ecoboost and there has been chat of a Mustang MR350 and MR400. And some yanks have the Mustang Ecoboost over 500BHP already! So i would say the Focus RS will get some nice treatment in general too!
