Lamborghini Islero classic cars for sale

History of the Lamborghini Islero

Introduced at the 1968 Geneva Motor Show, the Lamborghini Islero was designed to follow the 400 GT in Lamborghini’s line-up. Its name, continuing Lamborghini’s tradition, draws from the fighting bull theme and specifically references a bull named Islero. The model was produced over a brief period, making it one of the rarest Lamborghinis today. With production limited to only 225 units from 1968 to 1969, the Islero’s bodywork was handled by Carrozzeria Marazzi, a coachbuilder formed by former employees of the defunct Carrozzeria Touring who had also worked on previous Lamborghini coupés. Marazzi’s new bodywork combined sharp, assertive lines with Italian sports car proportions. Despite innovative mechanical solutions and a powerful drivetrain, the Islero struggled with body quality issues, which contributed to its short production run.

Model History

The Islero is based on the mechanical platform of the 400 GT, but was intended as a more refined successor for Lamborghini’s range of grand tourers. Its successor was the Jarama, which continued some stylistic and technical cues while addressing market demands for improved quality. The Islero was initially produced in its standard form with 325-330 hp from the V12, then replaced by the Islero S in 1969. The S version featured updates such as wider fenders, increased power, larger brakes, and refinements in both exterior and interior design. When Jarama succeeded the Islero in 1970, Lamborghini increased production numbers gradually, but never recaptured the exclusivity of the Islero.

Technical Data

Special Editions and Collectible Models

The Lamborghini Islero S represents a key collectible variant, produced in 1969 as an updated version of the standard Islero. The S variant featured more powerful engine tuning, improved brakes, flared wheel arches, an enlarged hood scoop, and stylistic as well as ergonomic refinements in the cockpit. Only 100 units of the Islero S were manufactured, making it even rarer than the initial release.

Weak Spots and Common Issues

Buyers should be aware of several potential issues. Period reports mention variability in the quality of bodywork, particularly concerning the fit and finish of aluminium panels. Early examples sometimes suffered from limited corrosion resistance. Mechanical components, particularly the V12 and Lamborghini’s own gearbox, require specific knowledge for maintenance. Authenticity and completeness of documentation (e.g. original manual and engine handbook) are important for value retention. Always verify the originality of key components, including the engine, as Lamborghini can issue factory certification for matching-number cars.

Engine and Performance, Transmission and Handling

The Islero is defined by its 4.0-litre V12 engine, delivering an output of up to 330 hp (Islero S). Six dual Weber carburettors underpin its robust power delivery. The 0-60 mph sprint is achieved in 6.4 seconds, and top speed exceeds 154 mph in S trim. Roadholding benefits from independent suspension with dual wishbones at each wheel and specifically tuned shock absorbers, granting the car stability on both mountain passes and motorways. The 5-speed manual gearbox, developed internally, features synchromesh rings on each gear for swift and precise shifts. - Lamborghini Islero (Standard): 325 hp, classic notchback coupé body, 125 units produced.

• Lamborghini Islero S: 350 hp, broader fender flares, upgraded brakes, further interior refinements, 100 units produced.

Interior, Comfort, Exterior and Design

The Islero was shaped by Carrozzeria Marazzi with a clear nod to its predecessor, the 400 GT, but with sharper lines and a clean, understated profile. Notable exterior elements include retractable headlights and Campagnolo wheels. The interior was typically outfitted with high-grade leather, wooden steering wheel, and wooden gear knob—features that nod to Lamborghini’s luxury aspirations. The car offered seating for four, a rare trait among Lamborghini models, and the boot benefitted from the notchback design for additional practicality. Fog lamp options and specialist trim finishes added further distinction for period buyers.

Other Features

Some vehicles retain rare accessories such as period-correct fog lamps or original documentation. H-registration is available for historic vehicles in certain markets, and original Lamborghini certificates can be requested for cars retaining their factory engines.

Summary

The Lamborghini Islero stands as an exclusive and technically innovative classic GT, with only 225 cars built. Its highly developed 4.0-litre V12, sophisticated chassis, refined interior, and notable rarity combine to make it a standout grand tourer for enthusiasts seeking something truly singular within the classic Lamborghini spectrum.
