This 1969 Lamborghini Islero is one of 100 examples of the S variant produced during a single year of production. Chassis 6558 is said to have spent time in Switzerland before remaining under Dutch ownership through the 1990s and early 2000s, and it later spent several years on display in Kuwait. The car again changed hands in 2022 and was purchased by the selling dealer approximately one month ago. Finished in blue-green metallic, the car is powered by a 3.9-liter quad-cam V12 that breathes through six Weber carburetors and is mated to a five-speed manual transmission. Additional features include servo-assisted disc brakes, four-wheel independent suspension, 15” Borrani wire wheels, black leatherette and beige cloth upholstery over 2+2 seating, a wood-rimmed steering wheel, and Jaeger instrumentation. This Islero S is now offered in North Salem, New York, with a tool kit and a clean Texas title.

Introduced at the 1968 Geneva Auto Show, the Islero shared many of its underpinnings with its predecessor, the 400 GT, including a shorter, lighter version of the 400 GT’s 2,550mm-wheelbase tubular chassis and the V12 engine also utilized in the Miura. The Islero’s bodywork featured panels provided by Carrozzeria Bertone with assembly handled by Carrozzeria Marazzi. Named after a Spanish fighting bull, the Islero was produced in two versions, with the S variant entering production in 1969 with revisions including a larger hood scoop, six fender vents on each side, flared fenders, round side markers, fog lamps mounted ahead of the grille, front quarter windows, an air vent on the left sail panel, tinted glass, and a heated rear window.

This example is finished in metallic blue-green, and various imperfections in the finish are shown up close in the photo gallery below along with several paint-meter readings. Design features include pop-up headlights, high-mounted bumpers, dual side mirrors, a fender-mounted antenna, a lockable fuel-filler cap, and quad exhaust outlets.

Borrani wire wheels are secured by three-eared knock-offs and are wrapped in 215/17HR15 Pirelli Cinturato HB CN 12 tires, as is a matching spare housed in the trunk. The Islero model’s servo-assisted four-wheel disc brakes incorporated larger rotors for the S variant.

The cabin is trimmed in black leatherette and beige cloth over 2+2 seating with high-backed front bucket seats, while matching upholstery covers the door panels. Additional features include brown carpeting, a green headliner, shoulder belts, a wood shift knob, a central fold-down rear armrest, front and rear console-mounted ashtrays, a lockable glovebox, and power windows.

The three-spoke steering wheel features a wood rim and hub accent. It sits ahead of a wood-trimmed dashboard fascia housing Jaeger instrumentation including a 300-km/h speedometer, an 8k-rpm tachometer, a clock, and gauges monitoring oil temperature, coolant temperature, oil pressure, amperage, and fuel level. The five-digit odometer shows 60k kilometers (~37k miles), approximately 20 of which have been added under current ownership. The S variant featured rocker-style switchgear in lieu of the Series I Islero’s toggle switches.

The 3,929cc 60° V12 features an aluminum block, aluminum cylinder heads with dual overhead camshafts on each bank, six Weber 40 DCOE carburetors, and twin distributors. Output for the S variant was factory rated at 345 horsepower. Shifting is via a Lamborghini-built five-speed manual gearbox with synchromesh on all gears. The independent suspension incorporates double wishbones, coilover shock absorbers, and anti-roll bars at front and rear. The rear suspension was revised for the Islero’s S variant to accommodate stronger braking.

The data plate above reads “Lamborghini 400GT 2+2/1*6558*” and the VIN on the Texas title is listed as 400GT22116558.
