About the Renault 18
The Renault 18 replaced the Renault 12 and served as the company's mid-range offering throughout the 1980s. Available as a four-door saloon or five-door estate, it featured front-wheel drive, independent suspension, and a choice of petrol and diesel engines ranging from 1.4 to 2.1 litres. The Turbo and GTX variants offered sportier performance, whilst the estate versions proved particularly popular with families and tradespeople.
Build quality was typical of French cars of the era, with comfortable seating and a spacious cabin. The Renault 18 gained a reputation for reliability when properly maintained, though rust protection was less effective than contemporary rivals. Today, these vehicles are increasingly sought after by classic car enthusiasts, with well-preserved examples commanding premium prices.
What Affects Renault 18 Prices
Condition is the primary price determinant for Renault 18 models. Rust is the biggest concern, particularly in sills, wheel arches, floor panels, and around the windscreen. Vehicles with documented rust treatment or those stored in dry conditions fetch significantly higher prices. Original, unmodified examples are more valuable than modified cars, especially for Turbo models.
Mileage impacts value, though a well-maintained higher-mileage car often proves preferable to a neglected low-mileage example. Estate versions typically command slightly higher prices due to their practicality and scarcity. Service history is crucial—comprehensive records demonstrating regular maintenance add substantial value. Rare colour combinations, original specification features, and period accessories all enhance desirability amongst collectors.
Buying Tips for a Used Renault 18
Inspect thoroughly for rust before purchasing any Renault 18. Check all vulnerable areas including jacking points, inner wings, and the spare wheel well. Surface corrosion often hides more serious structural problems underneath. Ensure all electrical components function correctly, as replacement parts are becoming increasingly difficult to source.
Verify the engine starts easily and runs smoothly without excessive smoke or unusual noises. Check for oil leaks around the engine and gearbox. Test the clutch operation and gearbox synchronisation on all gears. Examine suspension bushes and ball joints for wear. Request evidence of timing belt changes—failure can cause expensive engine damage.
