Rover 3.5 Litre classic cars for sale

History of the Rover 3.5 Litre (P5B)

Launched in 1967, the Rover 3.5 Litre marked the final and most refined evolution of the P5 series, first introduced in 1958. Originally pitched as a luxury saloon for discerning British buyers, the P5 grew in reputation thanks in part to the model’s regular use by Prime Ministers and members of the Royal Family throughout its production. The P5B suffix signified the adoption of the lightweight 3.5-litre V8 engine—derived from Buick America—ushering in a new era of performance and comfort for Rover. Production continued until 1973, with more than 9,000 coupes and over 11,500 saloons built. The P5B’s stately presence, genuine luxury credentials, and historic political connections have given it a special standing in British classic car culture.

Model history

The P5 series saw several major iterations. The original MkI (1958) featured a six-cylinder engine and modern conveniences like power brakes and optional automatic transmission. MkII (1962) introduced higher output and new body styles, including a two-door coupé. MkIII (1965) provided mainly cosmetic upgrades. The 1967 P5B iteration fundamentally redefined the series, introducing the now-famous V8 engine and further enhancing interior quality. Production ceased in 1973, succeeded by the Rover SD1, though the SD1 took a much different approach, targeting the executive market with a more modern design ethos.

Highlights and special features

Distinctive for its Buick-derived 3.5-litre V8 engine, the P5B combined 160 horsepower with impressive low-end torque—more than its inline-six predecessor could offer. The model came equipped as standard with 3-speed Borg Warner automatic transmission and variable-ratio Hydrosteer power steering. The interior set a benchmark with plush seats, real wood dashboards, and authentic materials. Externally, details like the '3.5 Litre' badge, quad headlights with paired fog lamps, and chrome Rostyle wheels marked out the P5B. Original colour palettes ranged from Admiralty Blue to Arden Green, including two-tone finishes. Both coupe and saloon versions rolled off the line, but only 402 left-hand-drive examples were produced—making them especially noteworthy today. The P5B was frequently nicknamed the 'Poor man's Rolls-Royce' due to its opulent trappings at a more accessible price point.

Technical data

Special Editions and Collectible Models

Among the standard production, left-hand-drive (LHD) versions of the P5B are especially rare, with just 402 units produced. Coupé versions, due to their sportier styling and lower production figures compared to the saloon, also rank as particularly collectible within the classic car community.

Weak Spots and Common Issues

No significant weak spots or issues specific to the Rover 3.5 Litre P5B are noted in our current data. However, as with any vehicle of this age, attention to rust in the bodywork—particularly the sills and undercarriage—is advised, and originality of interior materials may affect value.

Engine, Performance, Transmission and Handling

The heart of the P5B is its 3.5-litre, all-aluminium V8, sourced from Buick and refined by Rover's engineers for enhanced torque and reliability. Producing around 160 PS, it’s paired to a 3-speed Borg Warner automatic transmission, which, combined with high torque, makes for relaxed, effortless highway cruising. The suspension and braking systems were developed for comfort, making the P5B particularly suited for long-distance touring. The steering’s variable ratio and the automatic gearbox assure a refined, smooth ride.

Other relevant features

The P5B has made several film appearances, notably in the biopic 'The Life and Death of Peter Sellers,' where a burgundy example complemented the film’s period tone. Many surviving cars still come with comprehensive documentation, including original handbooks and provenance records, supporting their appeal.
