Yeah, Evo4's are nice. Check to make sure theres no probs with the rear diff, no knocking etc. as apparantly thats a common problem on them. Always take it for a blast first, if its been sitting for a while, the plugs tend to suffer, my mate had one before which had been sitting and when he put his foot down, the sparks were screwed and the car was missing like a bitch! Check the actuator as well, make sure it isnt rusted solid as thats what happened on my mate and the wastegate wouldnt open, boost cut anyone?
