Lamborghini 400GT Monza

The Lamborghini 400 GT Monza in brief

The 400 GT Monza is a one-off car. It was produced in 1966 by the Giorgio Neri and Luciano Bonacini workshop—the same craftsmen entrusted by Ferruccio Lamborghini in 1963 with the production and assembly of the first Lamborghini prototype, the 350 GTV chassis.

The base chassis is from the 350 GT, and under the bonnet sits the V12 engine from the 400 GT model. Initially, the car was named the “400 GT Neri & Bonacini,” but the shorter name “Monza,” with its racing heritage, was ultimately chosen.

Design and technology

The body is hand-built from aluminium and was modified several times during its creation. The appearance differs greatly from contemporary Lamborghinis: a long engine bonnet, a chopped Kamm-type rear end, a very low and raked windscreen, and non-functional air vents with grilles behind the front wheels.

The roll bar is integrated into a very thick C-pillar, restricting the driver's rearward visibility. Many believe the design bears a resemblance to other Italian sports coupés of the time, such as the Bizzarrini 5300 GT Strada.

History: built for racing, but never raced

It is believed that the car was created for an unknown American client who wanted to compete in the 24 Hours of Le Mans. Due to homologation issues, the Monza never raced, and the client, it seems, never received the car.

Instead, in 1967, it was exhibited at the Barcelona Motor Show on the stand of Lamborghini importer Amato. There, it was purchased by a wealthy Spaniard, and the car remained in his family for many years.

Where it is now and whether it can be purchased

In 1996, the auction house Brooks (now Bonhams) discovered the Monza in a warehouse when the heirs of the original owner asked them to appraise other cars in their collection. After nine years of negotiations, in December 2005, the car was sold at a Bonhams auction in London.

Since the car is unique, purchasing it is strictly for collectors, and it can only be seen at rare classic car events where the owner presents it to the public.

Monza and series 400 GT

400 GT Monza — a rare example of what an early Lamborghini could look like with a bespoke body. If you're interested in a genuinely purchasable model from that era, look for a series-production 400 GT.
