Lamborghini Islero

Late-1960s / early-1970s front-V12 Lamborghinis were built in very small numbers and passed through many hands. For the Islero specifically, the 'S' cars are visibly and mechanically distinct — bonnet vent, revised suspension, revised interior — and are more sought after than the base GT. Confirm chassis number, engine number and gearbox number match the factory build book; a Polo Storico heritage certificate is the strongest paper the market recognises.

Marazzi-built steel bodies rust in the sills, floors, rear arches and around the rear window surrounds. Cars presented as restored must be inspected on a lift with a paint-depth gauge; superficial paintwork over unresolved structural corrosion is common and materially resets value.

The four-cam V12, ZF five-speed gearbox and Salisbury rear axle are robust but specialist-served. Verify carburettor sync, cold-start behaviour, oil pressure at temperature, cambelt / timing-chain history and evidence of recent service. A drivetrain rebuild is a five- to six-figure exercise and should be reflected in price.

The base and later 'S' cars (Islero and Islero S; Jarama GT and Jarama GTS) are visibly and mechanically distinct — power outputs, bodywork details and interior trim differ. Verify configuration against the factory build book; an 'S' badge on a base car is a not-uncommon story that must be reconciled before any premium is paid.
