Look out for accident damage. Stonechipped front should be visible, if not may have been repainted. Scuffed alloys, If its standard, make sure its not been externally tweeked, which is a possible sign its been mapped and reset to standard. I always question why people do this, as makes it less saleable as you dont know how much boost the car has been using. Check the clutch by putting it in 4th and flooring it from low revs to check for slip. Tyres are expensive. Plastics inside can be fragile. Drivers seat can rock from side to side, but Ford did mod this. CV's can rumble on full lock. Sloppy handling can be wishbones on the front and or rear bushes. Its getting to that age like mine at 50 k miles.
