TRANSMISSION – A careless gear lever that tilts towards the fifth may be a weak return spring, but it is an expensive solution. The difficult selection of first and second gear may be due to low hydraulic pressure caused by heating of the clutch hose. Check that the diff supports are safe because they can flex and crack the boot floor.
BRAKES AND SUSPENSION – Listen for loose upper suspension mounts hitting the chamois. They fail every 60,000 miles or so. Look for stiff disc tweezers, a common problem. Check to see if the suspension has been checked or, more likely, improved with Bilstein shocks and that you are satisfied with the results.
BODY – Serious corrosion is likely to be related to an accident. Still, check the rear wings, windowsills, and the meeting point between the bonnet and bumper. Check that the rear window is securely fastened and that the rear windscreen wiper is working.
INTERIOR – Beware of oscillating seats, sticky electric windows (grease mechanism) and a faulty main light switch.
