For a gooden low millage you'd be looking at around the 6/8k mate. There good money and rare to come to across in such good nick and great milage Usuall lookouts are rust especially under the bodykit, arches, underneith. around the windsreen, battery tray, inner wings, fuel tank etc etc. Check the rear tail, make sure there are blank plugs for where the screws are as there rare as rocking horse shit and dout you'd find any more. Check the turbo for smoke, rattles in the engine etc etc. Good luck mate
