im goin to look at an astra on wednesday, because im thinking about buying one. its a 2.0 sri 3dr (mk4, but cant remember milage. something like 2000 and 70k miles i think). i think its been lowered and has uprated brakes too, as well as an irmsher grille. makes me think it might have been given a bit of a raggin. is there anything i should look out for? any signs of wear and tear etc?
