Top 10 Most Expensive Car Accessories in the World

Rolls-Royce Phantom VIII 2018 seems to evolve from the familiar stance and comfort of the Phantom VII, with smoother curves and edges to differentiate it from its predecessor. The spacious interior and rear-hinged doors of the Phantom offer easy access, a crucial feature for stylish passengers heading to an opera house or Michelin-starred restaurant.

Inside, two adults enjoy ample space to stretch out. The bench can seat three, but Roll-Royce offers a two-seat rear configuration for $34,400. For those requiring more room (perhaps professional basketball players), the extended wheelbase “EWB” version of the Phantom is the solution.

The individual seat configuration is also available with a fixed center console and a newly introduced reclining seat for long trips to the grocery store. The console can be upgraded with a built-in drinks cabinet, featuring champagne flutes, whisky glasses, decanters, and a cooler. Rear-seat passengers can relax in their private space, sip their favorite drinks, and enjoy the new “Library” feature, which allows them to view the owner’s selected art pieces.

Sleek aerodynamic features, delicate natural curves, and the stylish contours of a unique sports car often awaken the senses, evoking admiration and envy. However, another key element that plays a significant role in creating the impression of a Ferrari is its wheels.

Forging and casting are two common methods used to manufacture wheels. A forged wheel is made by applying extreme pressure to a solid aluminum billet, squeezing it between molds. This process results in a dense, strong, and lightweight product. While forged wheels are commonly used for high-performance sports cars, diamond-cut forged wheels undergo a process that provides an ultra-glossy finish. A close-up inspection reveals tiny grooves precisely cut into the aluminum surface, resembling the back of a CD. When light reflects off these ridges, it gives the alloy wheel a brilliantly shiny appearance.

Ferrari took this process even further. While the diamond-cut alloy wheels are stunning, they weren't quite dazzling enough for their unique LaFerrari, a supercar worth over $2 million. Therefore, they offer buyers an upgrade to wheels with actual diamond-cut finishes. The result is breathtaking. Diamonds may be a girl's best friend, and they may last forever, but at $47,440, they help set the limited-production LaFerrari apart from any other supercar.

For buyers of the Mercedes Maybach, interior finishes in wood, aluminum, or carbon fiber may not be exclusive enough to satisfy their high-end tastes. For the discerning shopper, Mercedes-Benz offers an option for stone interior trim through its bespoke Designo customization program.

The Designo stone trim is made from granite, one of the hardest stones available. Skilled artisans at Mercedes carefully select the finest pieces, slicing them into wafer-thin sheets and finishing them using a patented method. These granite panels are then shaped to fit the vehicle’s interior, combining with other materials to create a distinctive aesthetic. The stone's unique veining creates a shimmering effect that changes with the light, giving the interior a one-of-a-kind appeal. Despite the notion that stone might be heavy, the granite panels are only 1mm thick.

It seems fitting that a Mercedes Maybach, with a base price of $169,595, should be adorned with the same granite used in high-end kitchens across the country. This granite interior trim adds a staggering $58,000 to the cost of the vehicle. However, there are even more expensive packages available for the Maybach Landaulet and a Luxury package that further elevates the car's opulence.

The Pagani Huayra carries a hefty price of $1.4 million, putting it in the same category as other elite hypercars like the LaFerrari Aperta and McLaren P1. Its base price is steep, but the extensive list of optional upgrades takes things even further, making Porsche's premium options seem like a bargain.

With this price tag, buyers receive a 6.0-liter twin-turbo V12 engine from AMG, producing 753 horsepower and 738 lb-ft of torque. The car features active aerodynamics, carbon-titanium construction, and an opulent interior complete with Italian leather and aluminum controls. While carbon-ceramic brakes, Bluetooth, and a touchscreen navigation system come standard, many of the optional features require a significant additional investment.

Some of the standard upgrades for the Pagani Huayra are particularly costly, such as a $2,000 parking sensor, a $6,700 rearview camera, and a $20,425 seven-piece luggage set. Buyers who prefer black titanium interior trim will need to pay an extra $10,900, and applying the same treatment to the exterior chrome costs another $8,000. Premium leather upholstery is priced at $10,800. Additionally, some of the more extravagant options include a two-tone carbon fiber exterior package for $81,300—more expensive than a Porsche Boxster. For those looking to fully upgrade the body with carbon fiber, the cost is a staggering $153,700.

Each year, only four Breitling timepieces are crafted specifically for Bentley, making it one of the most exclusive options for any car, and certainly one of the priciest. A single artisan at Breitling creates these bespoke watches every three months.

The Mulliner Tourbillon features a 28mm case made from solid 18-carat gold, available in both pink and white gold. The dial can be crafted from either white mother-of-pearl or black ebony wood. At the 3, 6, 9, and 12-hour positions, eight diamonds mark the hours, and a small tourbillon window at 6 o'clock showcases this sophisticated mechanical feature, often found in luxury Swiss watches. The back of the case is hollowed out to allow natural light to illuminate the dial, providing a glimpse into the intricate inner workings, including a 22-carat gold balance wheel.

This analog watch requires periodic winding, but Bentley has introduced an innovative electrical mechanism that ensures the watch remains powered, even when the car is not in use for extended periods. With the base price of the Bentley Bentayga at $232,000, it already belongs to the luxury SUV class, but the $170,000 Breitling Watch option further elevates it to unparalleled levels of exclusivity.

When Bugatti introduced the new Chiron, a successor to the immensely successful Veyron Super Sport, the company proudly called it the "fastest, most luxurious, and most exclusive sports car in the world." While there is significant competition in the high-performance supercar market, Bugatti holds a clear advantage. They only needed to refine the Veyron, a car that had dominated the supercar world for a decade, to make it the fastest road-legal car in the world. The Super Sport achieved a Guinness World Record in 2010 with a top speed of 257.87 mph.

While the Veyron produced 1,184 horsepower from its W16 engine, the Chiron needed to step up to maintain its lead. Bugatti equipped the Chiron with a W-16 8.0-liter engine that delivers 1,479 horsepower and 1,180 lb-ft of torque. Not content with just that, Bugatti fine-tuned the car even further with the Chiron Sport, which offers the same power as the standard Chiron but with an even higher top speed thanks to weight-saving measures.

Bugatti engineers went so far as to replace the windshield wipers with carbon fiber as part of their weight reduction program, saving 39 pounds in the process. The Chiron Sport also features modified suspension and torque settings, and its price tag of $3.6 million is about $1 million more than the standard Chiron. For those seeking to shave off even more weight, Bugatti offers the full carbon fiber body option for an additional $300,000!

While the base price for all Ferrari models is already higher than what many people pay for a house, the options available can drive the total cost of owning one through the roof. Even the ‘entry-level’ Ferrari Portofino, with its 3.9-liter twin-turbo V8 engine producing 591 horsepower and a starting price of $215,000, can easily double in price depending on the chosen options. The Portofino comes with a few luxury features, including a retractable hardtop, a 10.2-inch infotainment screen, and rear seats that are far too cramped for those of average size.

Perhaps the priciest option available for any Ferrari is the carbon fiber front end, priced at $333,500, but even the smallest upgrades aren’t cheap: Painted brake calipers will add $1,519, a folding rear seatback will set you back $1,687, and multiple front fascia options cost another $1,687. Other upgrades include a fire extinguisher at $1,097, a front parking camera for $6,075, colored rev counters for $776, a cigarette lighter for $811, Ferrari-logo floor mats for $1,350, Apple CarPlay for $4,219, and a must-have carbon fiber cup holder for $2,531, pushing the total even higher.

With the Jaeger-LeCoultre Amvox2 Transponder 2014 watch, you can lock and unlock your Aston Martin, as well as activate its headlights. Aston Martin drivers can now program and control these functions for all models currently in production. The key difference between the 2014 version of this watch and the original 2006 model lies in the addition of a remote door locking/unlocking feature. The new Amvox2 Transponder integrates this function, allowing the wearer to control their Aston Martin’s door locks directly from the watch.

Some may recall that earlier versions of the Amvox watch included this feature. Indeed, Jaeger-LeCoultre initially developed the concept for the Amvox DBS Transmitter, Amvox2 DB9 Transmitter, and Amvox2 Rapid Transmitter. These earlier models were specifically designed for the Aston Martin DBS, DB9, and Rapide. However, with the Amvox2 Transponder, Aston Martin drivers now have the ability to control these functions across all current models in production through a miniaturized transmitter integrated into the back of the watch face.

Rolls-Royce cars are known for their unrivaled luxury, a level of opulence that sets them apart. But what could take a Phantom to the next level of extravagance? Some features include a Theater System, Personal Recliner Seats, and Bulletproof Glass. This one-of-a-kind Rolls-Royce Phantom, delivered to its owner in Hong Kong, boasts all of these luxury elements, along with a special rear cabin divider, or as it's officially termed, the 'Privacy Suite.'

This particular Rolls-Royce Phantom features an electrochromic glass partition that separates the front and rear cabins. The glass can be toggled to a frosted state at the rear passenger's request, with the default mode being clear. Additionally, the entire partition is soundproofed with advanced acoustic materials, ensuring that front passengers cannot overhear any conversation in the back. This technology uses a specialized frequency to absorb sound. If desired, rear passengers can use an intercom system to communicate with the driver, and the driver can also 'call' the rear passengers, who can accept or decline the call.

When it comes to swapping out wheels or rims for a 918 Spyder, owners often face some key considerations. A common dilemma arises when deciding to upgrade to a new wheel size or purchase new rims because the current set feels outdated. The lightweight forged magnesium wheels come with a sleek silver finish for a sophisticated look. These magnesium wheels on the 918 Spyder are exceptionally light, significantly reducing the vehicle's overall weight.

Designed as a single-piece forged magnesium alloy in a sporty Porsche RS Spyder style, these wheels are fully finished in satin black. The magnesium wheels for the 918 Spyder provide a remarkable weight saving, around 14.9 kg less compared to the standard wheels. This design uses minimal material for low weight while still maintaining high stability and strength, typical of a high-performance motorsport design. Additionally, the rim base, hub mounting areas, and the individual spokes (with the rear faces of the spokes machined) are precision-engineered for maximum performance.
