I always wanted one, basically from when they came out.
Was in a position last year to buy one and opted for a slightly modded one, mine runs about 300bhp with updated suspension and brakes.
I absolutely love it and like said above, it feels like a much more modern and well built RS turbo. Great handling, noise and drive and still has the feeling of a rare RS for me.
I've also got a 4x4 Saff and I must admit I find the Focus more fun to drive. It feels a lot quicker and I'm not as scared to break it lol
