At Automotive Addiction, we’re no strangers to rare and thrilling performance cars – but few ignite the senses quite like this amethyst black McLaren 600LT. Sitting proudly in McLaren’s “Longtail” lineage, the lightweight 600LT supercar is the hardcore, track-honed evolution of the 570S. It’s lighter, louder, sharper, and built to devour apexes and adrenaline in equal measure.

But what really sets this 600LT supercar apart is its staggering £44,615 worth of optional extras – headlined by three distinct carbon-fibre exterior packs and an MSO-defined paint finish that turns this already-wild machine into a road-legal work of art.

Let’s dive into what makes this 600 Longtail

so special – and how the optional carbon packages take things to a new level of exclusivity and performance presence, creating what is arguably the closest thing to the revered P1 hypercar, but for a fraction of the price.

The 600LT – The Purest Driver’s McLaren?

The 600LT is McLaren’s love letter to performance purists. Based on the 570S, it undergoes a dramatic transformation in the name of speed and engagement. Weighing 96kg less than the 570S, it features a carbon-fibre Monocell II chassis, stripped-back Alcantara-clad interior, carbon-ceramic brakes, and McLaren’s iconic dihedral doors.

Under the rear deck of this McLaren 600LT for sale lies the familiar 3.8-litre twin-turbo V8, tuned to 600PS (592bhp) and 620Nm of torque. This power is sent to the rear wheels via a 7-speed Seamless Shift Gearbox (SSG), which comes alive with ignition cut gearshifts, launch control, and even a cheeky burnout mode – just in case you want to make an impression on the pit lane exit.

The 600LT will sprint from 0–62mph in 2.9 seconds and on to a 204mph top speed. But numbers only tell part of the story – because this thing feels as raw and alive as anything south of a McLaren Senna. It’s all helped by stiffer engine and transmission mounts, plus those mesmerising top-exit exhausts that spit flames with every aggressive downshift.

Carbon-Fibre Exterior Package 1 – £3,240

This McLaren 600LT’s first carbon pack starts with subtle but purposeful enhancements.

• Carbon-Fibre Extended Side Intakes
• Carbon-Fibre Door Mirror Casings

These additions complement the aerodynamic lines of the 600LT while sharpening its visual attitude. The extended intakes hint at extra airflow, while the carbon mirrors reduce weight at the car’s extremities – proof that in a McLaren, every gram counts.

Style Impact: ★★★☆☆

Functionality: ★★☆☆☆

Exclusivity Rating: 7/10

Carbon-Fibre Exterior Package 2 – £5,700

This is where the McLaren 600LT starts to look truly track-bred.

• Carbon-Fibre Front Splitter with Integrated Twin Endplates
• Carbon-Fibre Sideskirts with Aero Winglets
• Carbon-Fibre Rear Bumper with Integrated Diffuser
• Carbon-Fibre Rear Bumper Aero Fins

These additions do more than just look good. The aggressive front splitter and rear aero features add meaningful downforce, stabilising the car at speed and giving it razor-sharp handling on circuit. The diffuser’s complex design helps manage airflow while cooling the rear-mounted exhaust system.

Style Impact: ★★★★☆

Functionality: ★★★★☆

Exclusivity Rating: 8/10

Carbon-Fibre Exterior Package 3 – £9,950

The pièce de résistance for those seeking the full visual and performance edge.

• Carbon-Fibre Rear Deck with Integrated Exhaust Outlets
• Carbon-Fibre Door Inserts
• Carbon-Fibre Service Cover

The carbon rear deck is a particular highlight – surrounding the flame-spitting top-exit exhausts with shimmering carbon weave, it transforms the rear end into a motorsport-grade masterpiece, while shedding yet more mass high up on the car, helping to further lower the McLaren 600LT’s centre of gravity. The door inserts give the side profile a unique layered look, while the carbon service cover adds functional beauty under this McLaren supercar’s rear clamshell.

Style Impact: ★★★★★

Functionality: ★★★☆☆

Exclusivity Rating: 9/10

MSO Defined Amethyst Black – £6,120

If the carbon wasn’t enough to set this 600LT supercar apart, it also wears MSO Amethyst Black, a bespoke McLaren Special Operations paint that shimmers between black and deep purple under changing light.

Subtle in shadow and electric in sunlight, this colour is both menacing and elegant. It’s the perfect match for the carbon upgrades and gives the car an identity all its own.

Uniqueness: ★★★★★

Visual Drama: ★★★★☆

Paint Code Bragging Rights: 10/10

Total Optional Extras: £44,615

Combined with a host of other highly desirable extras such as the £2,990 Designer Alcantara Interior package, the £5,500 Carbon-fibre Interior upgrade, the £3,860 Security package and £1,140 Ultra-Lightweight 10 spoke forged wheels, these upgrades take the McLaren 600LT from a focused road weapon to a carbon-draped masterpiece. Few examples will feature this full suite of options, making this spec (that totals an unbelievable £44,615 in extras alone) ultra-desirable for collectors and enthusiasts alike.
