I have just sold my impreza sti type uk and got a 56 plate st3 and I am more than happy with it
obviously its not as quick as the impreza but its a much smoother car to drive. Definately a car you could use everyday.
the one your looking at I think is a little overpriced although quite well specced I was also told to keep away from the orange ones as if you need any paint doing on them its really expensive?
