Lamborghini Islero: A Comprehensive Guide

The Lamborghini Islero, produced from 1968 to 1970, occupies a unique and often overlooked space in Lamborghini's history. A 2+2 grand tourer, it was conceived as a replacement for the 400 GT 2+2, offering enhanced performance, refined styling, and improved comfort compared to its predecessor. While production numbers were relatively limited, the Islero remains a desirable classic for enthusiasts seeking a blend of Italian design, V12 power, and comfortable long-distance touring capabilities.

1. Introduction

The Islero emerged during a turbulent period for Lamborghini. The company was expanding, but financial stability was always a concern. The Islero aimed to streamline production and offer a more refined driving experience while retaining the brand's core values of performance and exclusivity. It's important to note that the Islero name derives from a Miura bull, a nod to Ferruccio Lamborghini's passion for bullfighting. The car was designed by Mario Marazzi after Carrozzeria Touring, who built the 400 GT 2+2 body, went into liquidation. The initial design was penned by Touring but ultimately finalised and produced by Marazzi.

2. Generations

1968-1969: Islero 400 GT

  • Key Features: Original Islero design. Powered by a 3,929 cc (3.9 L) V12 engine producing 325 bhp (242 kW; 330 PS) at 6,500 rpm.
  • Changes: Featured a distinctive Kamm tail design, independent suspension all around, and disc brakes on all four wheels.

1969-1970: Islero S

  • Key Features: Improved version of the Islero. Engine output increased to 350 bhp (261 kW; 355 PS) due to revised carburetors and camshaft timing.
  • Changes: Externally, minor changes included slightly flared wheel arches, revised badging, and improved ventilation. Interior received some updates to improve comfort and ergonomics. Brakes were also upgraded.

3. Reliability & Common Issues

Owning a classic Lamborghini Islero requires a thorough understanding of its potential weaknesses. While the V12 engine is generally robust, proper maintenance is crucial. Parts availability can be challenging and expensive.

  • Engine: The V12 engine, while powerful, can suffer from issues related to the carburetors (especially if neglected), oil leaks, and cooling system problems. Regular valve adjustments are essential. Look for signs of overheating (warped heads, coolant leaks).
  • Electrical System: Like many Italian cars of the era, the Islero's electrical system can be a source of frustration. Wiring can become brittle, and connectors can corrode. Ensure all electrical components (lights, gauges, etc.) are functioning correctly.
  • Suspension: The independent suspension, while offering good handling for its time, requires regular inspection and maintenance. Bushings can wear, and shock absorbers can leak. Listen for noises from the suspension during test drives.
  • Brakes: The four-wheel disc brakes can suffer from corrosion and sticking calipers, particularly if the car has been stored for extended periods. Ensure the brakes are responsive and free of excessive noise or vibration.
  • Bodywork & Rust: Check for rust, particularly in the lower body panels, around the wheel arches, and under the floors. Accident damage may be concealed, so a thorough inspection is essential. The aluminum body panels can be susceptible to corrosion if not properly maintained. Marazzi's craftsmanship was generally good, but panel fit can vary.
  • Interior: The interior trim can deteriorate over time. Leather can crack and fade, and wood trim can become damaged. Replacing or restoring interior components can be expensive. Ensure all gauges and switches are functioning properly.
  • Fuel System: The fuel system, including the fuel pump and lines, can be prone to leaks and clogging, particularly if the car has been sitting. Check for fuel smells and signs of leaks.

Expert Tip: A pre-purchase inspection by a specialist familiar with classic Lamborghinis is highly recommended. Don't be afraid to spend money on a thorough inspection; it could save you significant expenses down the road.

4. Driving Experience

The Lamborghini Islero offers a unique and engaging driving experience. The V12 engine provides exhilarating acceleration and a distinctive soundtrack. While not as raw as some of Lamborghini's earlier models, the Islero offers a more refined and comfortable ride, making it suitable for long-distance touring.

Pros:

  • Powerful V12 Engine: Provides impressive performance and a unique soundtrack.
  • Elegant Design: The Islero's styling is distinctive and appealing, especially the improved design of the S model.
  • Comfortable Ride: Relatively comfortable for a car of its era, making it suitable for grand touring.
  • Exclusivity: Limited production numbers make the Islero a rare and desirable classic.

Cons:

  • Challenging Maintenance: Requires specialized knowledge and can be expensive.
  • Parts Availability: Parts can be difficult to find and expensive.
  • Ergonomics: The driving position and interior layout are not as ergonomic as modern cars.
  • Reliability: Can be prone to mechanical and electrical issues, particularly if not properly maintained.

5. Buying Advice

Purchasing a Lamborghini Islero requires careful consideration. Condition is paramount, and a well-documented history is highly desirable. The Islero S is generally considered more desirable due to its increased power and improvements.

  • Years to Look For: 1969-1970 (Islero S) are generally preferred due to the performance upgrades and improvements.
  • Years to Avoid: No specific years to avoid, but prioritize condition over model year. A well-maintained 1968 400 GT is preferable to a poorly maintained Islero S.
  • Key Considerations:
    • Rust: Thoroughly inspect for rust, especially in the usual trouble spots.
    • Engine Condition: Have the engine compression tested and look for signs of leaks or damage.
    • Documentation: Look for complete service records and documentation of any previous restoration work.
    • Originality: While some modifications may be acceptable, prioritize originality if possible.
    • Pre-Purchase Inspection: A must-have before committing to a purchase.
  • Market Value: Islero values can vary significantly depending on condition, originality, and provenance. Research recent sales to get an accurate understanding of the current market value.

Final Thoughts: The Lamborghini Islero is a rewarding but demanding classic. With careful research, a thorough inspection, and a commitment to regular maintenance, it can provide a unique and unforgettable driving experience. It's a car that demands respect and understanding, but in return, it offers a glimpse into a fascinating era of automotive history.
