Engine: If the engine idles roughly or shudders, it could be experiencing an ECU software fault. A remap of the ECU should fix this issue.
Steering: A knocking sound when you’re turning at lower speeds could mean the steering damper needs replacing. It’s an inexpensive part and one that’s easy to install, though.
Clutch: A common issue with early models is transmission throw bearings wearing out, and this can quickly lead to clutch fork failure. Unusual sounds and feelings when you’re applying the clutch are signs. It can be resolved by replacing the worn bearing.
Transmission: Check that second gear engages smoothly. The triple-cone synchros can be slow to work when cold, causing an odd-feeling change. Some owners recommend pausing in neutral after first gear, then engaging second with a firm shove. Technicians recommend fresh fluid.
Body: Condensation usually arises in the rear lights after heavy rain. You can apply a seal to prevent this, but if the light has corroded or broken due to the moisture, you will have to replace it.
Interior: Complete a test drive and make sure there aren’t any rattles coming from the interior (or indeed the rest of the car). The biggest culprits are the rear seats and trim, parcel shelf and lower dashboard. On early cars, a rattle from the gear lever above 4000rpm was a common issue.
