I've got my Empeg in a 2000 Focus. if the UK version of the Focus is like the US version, the adapter kit was inexpensive, about ~20 USD. I have no idea how different the UK version is different from the US version, but I have over 75,000 miles on mine at the moment without a problem. I have the 2.0L four valve gasoline engine and it's great for a back-and-forth/work-car. I personally think this is a great compliment to the car, as I am a horsepower junkie (currently own a S10 Pickup with a 500HP Corvette LT1 & a Mustang with a 1200HP Turobcharged 5.0L) who drives cars real hard. The Focus is a great deal for the price, in the US.
