About the Renault 15
The Renault 15 was launched in 1971 as a stylish two-door coupé, designed to compete in the sporting GT market. Built on the Renault 12 platform, it featured distinctive fastback styling penned by Renault's design team. The model was available with a range of petrol engines from 1.3 to 1.6 litres, with the TS and TL variants being most popular in the UK. Production ceased in 1979, making survivors increasingly sought-after by classic car enthusiasts.
As a classic car from the 1970s, the Renault 15 appeals to collectors and enthusiasts who appreciate French automotive design from this era. Its rarity on UK roads has contributed to steady appreciation in values, particularly for well-maintained examples with documented history. The model's combination of practicality and sporting character makes it an accessible entry point into classic car ownership.
What Affects the Price of a Used Renault 15
Condition is the primary price determinant for Renault 15 models, with rust being the most significant concern. Examples with solid bodywork, particularly around sills, wheelarches, and the boot floor, command substantial premiums. Original, unmolested cars with matching numbers and factory specifications are increasingly valuable, whilst modified examples typically sell for less unless the work is of exceptional quality.
Mileage is less critical than condition for a classic car of this age, though lower-mileage examples with supporting documentation do achieve higher prices. Completeness matters significantly—cars with original trim, lights, and badges are worth more than those with missing or aftermarket parts. Service history, even if patchy, adds value, as does evidence of professional restoration work. The TS model with the larger 1.6-litre engine typically commands a 15-20% premium over standard variants.
Tips for Buying a Used Renault 15
Inspect thoroughly for rust, as corrosion is the biggest threat to these cars. Check all common rot spots including sills, front wings, door bottoms, boot floor, and the rear suspension mounting points. Original parts are increasingly difficult to source, so verify what's available before committing to a restoration project. A solid, running car requiring cosmetic work is often a better buy than a cheap example needing structural repairs.
Verify the engine number matches the documentation, as originality significantly affects value. Test all electrical systems, as period French electrics can be problematic and expensive to rectify. Join the Renault 15/17 owners club before purchasing to access knowledge, parts contacts, and potential pre-purchase inspection services. Budget for maintenance—whilst mechanically simple, these cars require specialist knowledge and patience. Consider storage and insurance costs, as classic policies typically require garaged storage.
