About the Peugeot 604
Launched in 1975, the Peugeot 604 was the French manufacturer's flagship model, designed to compete with executive saloons from Mercedes-Benz and BMW. Available exclusively with V6 engines ranging from 2.7 to 2.8 litres, the 604 offered refined performance and spacious accommodation for five adults. Production ceased in 1986 after approximately 153,000 units were built globally, making surviving examples increasingly rare in the UK market.
The 604 featured independent suspension, power steering as standard, and trim levels that included vinyl, SL, STi, and the range-topping GTi. Many models were fitted with the PRV V6 engine developed jointly with Renault and Volvo. Today, the 604 is considered a classic car, with enthusiasts valuing its blend of French styling and executive comfort.
What Affects Peugeot 604 Prices
Condition is the primary price determinant, with rust-free bodywork commanding significant premiums due to the model's susceptibility to corrosion, particularly around sills, wheel arches, and the front subframe. Original, unmodified examples with comprehensive service histories are worth considerably more than neglected or modified cars.
Mileage plays a crucial role, with sub-50,000-mile examples fetching top prices. Engine specification matters too—the later 2.8-litre V6 models are more desirable than earlier 2.7-litre versions. Interior condition, particularly original upholstery and functioning electrics, significantly impacts value. Rarity also influences pricing, with GTi models and estate variants (Break) commanding premiums over standard saloons.
Peugeot 604 Buying Tips
Inspect thoroughly for rust, as corrosion is the 604's biggest enemy. Check underneath the car, inside the boot, and all panel seams. The PRV V6 engine is generally reliable but requires regular oil changes; listen for tappet noise and check for oil leaks from the cam covers and rear main seal.
Verify that all electrics function correctly, including windows, central locking, and dashboard instruments, as parts are increasingly difficult to source. Check the condition of the automatic transmission if fitted—manual gearboxes are rare but more desirable to enthusiasts. Join the Peugeot 604 Owners Club UK before buying, as members can provide valuable advice and access to spare parts. Budget for maintenance costs, as specialist knowledge is often required and many components must be sourced from France or from breaking cars.
