The Appeal

Launched in 1990 as the successor to the legendary Lamborghini Countach, the Diablo took Lamborghini’s signature formula of dramatic styling and outrageous performance and pushed it even further. Named after a notorious fighting bull, the Diablo paired its angular, impossibly wide bodywork with a 5.7-litre naturally aspirated V12 capable of propelling the car beyond 200mph, a scarcely believable figure at the time. More than the numbers, though, it was the sense of theatre that defined the Diablo: the scissor doors, the thunderous soundtrack and the sheer physicality of the driving experience.

Unlike modern supercars, the Diablo belonged to an era before electronic driver aids softened the edges. Early rear-wheel-drive cars, with their heavy controls and manual gearbox, demanded real commitment from the driver, giving the car a reputation for being both thrilling and intimidating in equal measure.

Today, the Diablo is widely regarded as the last truly analogue V12 Lamborghini, the final chapter before Audi ownership brought a more polished and technologically sophisticated approach to the brand. Raw, dramatic and unapologetically excessive, it remains one of the defining supercars of the 1990s and a high point in Lamborghini’s long tradition of building machines designed as much to shock as to perform.

Believed to be the only Diablo finished in Metallic Agate Grey, this example is thought to have a genuine one-of-one specification. Right-hand drive cars are already scarce, but a unique-colour car with over 30 years of single-keeper provenance elevates this to a different level of collectability. The seller notes it has only been driven for servicing and maintenance purposes over the past 20 years whilst in Spain, maintaining the car's originality and low mileage.

It comes accompanied by the tan leather Lamborghini Diablo luggage set and the original factory exhaust, alongside the currently fitted chrome sports exhaust. The car has a service history with Portman Concessionaires up to 37,500 miles, followed by servicing carried out by Carrera Sports. Some previous invoices and MOT certificates are also included.

The car is presented in honest condition: the black leather interior and overall visual presence remain striking, though the vendor notes that it has been cherished as a collector's piece rather than a regularly used supercar, and will require a major mechanical refresh by the new owner before returning to the road. The seller suggests that potential buyers should organise their own inspection prior to bidding, to determine themselves what work is required to bring the car back to it's former glory.

Owning a Lamborghini Diablo was never about practicality; it was about theatre, excess and occasion. Few cars capture the spirit of the analogue supercar era quite like this, and fewer still survive with this level of provenance and originality. For the next custodian, this is not simply an opportunity to acquire a rare Lamborghini, but to own one of the defining poster cars of an entire generation.

The vendor suggests that potential buyers should organise their own inspection prior to bidding, to determine themselves what work is required to bring the car back to it's full potential

This is the kind of car that still turns heads for all the right reasons. The black leather interior with red piping gives it a proper late-’90s sports car feel, helped further by the sports seats, a chrome sports exhaust and staggered three-piece O.Z. Racing wheels filling the arches. It’s got all the essentials too; climate control, electric windows and mirrors, central locking, an adjustable steering wheel, and even its original Alpine cassette-stereo with amplifier still in place.

It isn’t a concours car, and it doesn’t pretend to be. There are some cosmetic imperfections, including paint blemishes on the lower doors and a small area near the wiper blade that would benefit from touch-up work. The seller notes that it has been cherished as a collector's piece during their custody; it would benefit from a major mechanical refresh by the new owner before returning to the road, and the vendor suggests that any potential buyer should organise their own inspection prior to bidding, in order to determine themselves what work is required to bring the car back to it's full potential. Honest, distinctive and full of character, it feels like a proper driver’s car from an era when supercars still had real personality.

The Mechanics

5.7-litre longitudinally-mounted V12 producing 485bhp with electronic fuel injection and dry-sump lubrication
Five-speed ‘dogleg’ manual transmission
Recent work reportedly includes: two new fuel pumps, two new fuel filters, two new air filters, fuel injectors replaced, oil and oil filter change, and a new battery
Major mechanical overhaul recommended by the vendor following 20 years of limited use; seller suggests that a potential buyer should organise their own inspection prior to bidding, in order to determine themselves what work is required to bring the car back to it's former glory
Electrical inspection to some fuses and relays recommended by the vendor
Clutch bleed and attention recommended by the vendor

At the heart of the car is a glorious 5.7-litre longitudinally mounted V12, producing 485bhp through a proper five-speed dogleg manual gearbox, exactly the sort of setup that makes every drive feel mechanical, involving and special. With electronic fuel injection and dry-sump lubrication, it has all the hallmarks of a serious performance car from an era when manufacturers were building machines first and worrying about refinement second.

The car has also seen a fair amount of recent maintenance, reportedly including new fuel pumps, filters, air filters, replacement injectors, a fresh oil service and a new battery. However, the vendor notes that a major mechanical refresh is recommended, having been cherished as a collector's piece during their custody, covering very few miles. Potential buyers are recommended to organise their own inspection prior to bidding, in order to determine exactly what work is required to bring the car back its full potential. The vendor notes that some electrical inspection to fuses and relays would be worthwhile, along with attention to the clutch, but overall it comes across as an honest example with the right fundamentals; the kind of V12 car that’s all about the noise, the feel and the occasion every time you turn the key.
