My sisters boyfriend is interested in getting an Impreza

Told him ot get an Evo but he wants a blue Impreza (normal Turbo 2000 AWD model will do him, not really interested in the WRX/STi stuff - all he wants to do is change to the P1 type front bumper and rear wing, add a zorst and

- tho he might lod in some nicer seats if poss)
So what should he be looking at spending on one, around S reg....
And what sort of running costs are likely?
