So here’s a question designed to divide opinion among supercar enthusiasts: how far is too far when it comes to bling for your car?
Let’s face it - we’ve all seen the photos. A Bugatti Veyron wrapped in python skin, a Lamborghini Aventador covered in Swarovski crystals, and a Rolls-Royce Ghost with a dashboard finished in actual meteorite. These rather extreme customisations create what we call the Marmite effect among supercar fans.
Whether you love or hate the thought of these adaptations and personal expressions of taste, one thing’s for sure: these cars certainly command a second look from passers-by, stop traffic in its tracks, and occasionally break the internet (as well as the hearts of supercar purists everywhere!).
Here at Elev8 Finance, we like to get down to the nuts and bolts of what and what doesn’t add up where supercar depreciation and appreciation are concerned. Does all that customisation actually harm or enhance the value of the car? We discuss more in this article.
Spoiler Alert! Before we begin, we’ll let you in on a little secret… the answer is somewhat complicated, but always fascinating. Read on to find out more.
Key Takeaways:
The UK supercar aftermarket customisation sector is estimated to be worth over £900 million annually
London is among the most active markets in Europe for extreme supercar personalisation trends
Factory-documented bespoke builds consistently sell at between 10% to 35% above equivalent standard-specification examples at auction
Non-factory modifications are among the top three value-reducing factors cited by specialist insurers and auction valuers
The Koenigsegg CCXR Trevita (built with real diamond-dust carbon fibre) sold at public auction for $4.8 million (approximately £3.8 million), showing that manufacturer-backed extreme builds can hold extraordinary value
Britain has a healthy appetite for ostentatious supercar culture - particularly, it seems, in London. According to data from the Society of Motor Manufacturers and Traders (SMMT), the UK is consistently one of Europe's top three markets for cars priced over £100,000, with registrations in that segment repeatedly outperforming the broader market even during periods of economic uncertainty.
The logic behind this is as follows: high-net-worth buyers tend to accelerate spending on luxury goods when equity markets wobble. And guess what? The bespoke modification industry for luxury vehicles has followed suit.
So much so, in fact, that the UK aftermarket customisation sector (covering everything from tasteful resprays to full diamond-encrusted overhauls) is estimated to be worth over £900 million a year.
If you live in or are a regular visitor to our capital city, you’ll know that London's Mayfair and Knightsbridge postcodes function as the unofficial showroom for some of the world's most extreme builds.
Let’s face it. Any conversation about extreme supercar customisation isn’t complete without the celebrity angle. The UK has produced, attracted, or been treated to some spectacular examples of these, so let’s take you on a little journey of what you may have seen over the years (or missed!):
American boxing champion Floyd Mayweather (a frequent visitor to London) has become perhaps the world's most recognisable collector of outlandish supercars. His fleet has included a white Bugatti Veyron, multiple custom Rolls-Royces, and a Koenigsegg CCXR Trevita: one of only two ever made, with one example selling at auction for approximately $4.8 million (around £3.8 million).
When Cristiano Ronaldo was playing for Manchester United, his supercar collection became as much a talking point as his football. His Bugatti Centodieci (one of only ten ever made, with a launch price of approximately €8 million (around £6.8 million)) was factory-authorised.
Limited production numbers and full manufacturer documentation make purchases like this an asset, not just a vanity purchase. His Lamborghini Aventador LP 700-4 and other additions to his collection received extensive coverage in the UK motoring press during his time in the North West, which only added to their resale value.
Every summer, London's streets (particularly Knightsbridge, Mayfair, and the King's Road) become an informal concours for supercars owned by ultra-high-net-worth visitors, many from the Gulf states.
These vehicles are frequently shipped to the UK specifically for the season, and commonly feature gold chrome wraps, full bespoke interior treatments, and in some documented cases, bodywork incorporating precious metals.
In 2014, a gold-plated Lamborghini Aventador attracted headlines around the world after being photographed in London. The plating alone was estimated to have cost a significant premium above the car's £260,000-plus base price. It was both spectacular and absurd. But from a resale perspective, it was essentially unsellable to 99.9% of the global buyer pool.
And that in itself is the central paradox of extreme supercar customisation. The more money you pour into personalising it, the smaller your audience of potential buyers becomes. Take this as an example: A stock Ferrari 812 Superfast can be sold to any sufficiently wealthy petrolhead on earth. Whereas a gold-plated, diamond-encrusted version of the Ferrari? Well, you're fishing in a very shallow pond indeed.
This is what industry insiders call the “spectacle premium". By that, we mean a car which becomes so unique that it transcends the normal rules of automotive valuation. These luxury vehicles don't depreciate like regular cars. They either appreciate - or they become unsellable curiosities. There is rarely a middle ground.
Perhaps no customisation divides opinion like the Swarovski treatment. Several Lamborghinis and Ferraris have received the full crystal encrustation - that’s right, thousands of hand-placed rhinestones covering every body panel. While we think they look genuinely stunning under studio lighting, pictured in rainy London or on the M25 motorway, much less so!
The resale problem is this: the crystals add negligible structural value, require specialist cleaning, can detach at speed (creating a genuine road safety issue), and must be completely removed before any serious bodywork can take place. So, you're essentially paying to make future repairs even more expensive.
A 2022 report by classic and specialist car valuation experts Hagerty found that significant non-factory modifications were among the top three value-reducing factors identified by specialist insurers and auction house valuers.
Our opinion is this: if the customisation requires a specialist to undo it before a mechanic can do anything useful, it's costing you far too much money - and time.
Let’s be clear - not all extreme personalisation destroys the value of a car. In fact, the collector car market has one reliable exception to the rule: reputable and aspirational brand collaborations.
One such example is the Bugatti Veyron by Hermès (called the Bugatti Veyron Fbg par Hermès). The result is a genuine co-design between the two luxury brands that commands a substantial premium at auction over standard Veyron examples.
Similarly, Ferrari's Tailor Made programme and McLaren's MSO (Special Operations) division produce factory-sanctioned bespoke vehicles that carry full manufacturer documentation and, more importantly, do not void the warranty.
However, the Rolls-Royce Bespoke division goes even further to protect the value of its vehicles. Every single commission is documented, photographed during the build process, and accompanied by a certificate of authenticity. And this process matters enormously at resale.
Yes, it does - and potentially significantly. Lenders assess the vehicle's achievable market value when structuring a finance agreement. This means extreme aftermarket modifications can reduce the number of potential future buyers, which in turn affects the vehicle's residual value and the lender's risk assessment.
We recommend always disclosing modifications to your finance provider before completing any agreement. At Elev8 Finance, we regularly help clients navigate the valuation process for heavily personalised vehicles - get in touch to find out more.
In most cases, yes. Factory-documented bespoke builds (such as those produced by Rolls-Royce Bespoke, Ferrari Tailor Made, or McLaren Special Operations) carry full manufacturer pedigree and typically hold their value considerably better than aftermarket work of a similar visual effect.
Specialist lenders and insurers treat these very differently, because the documentation is verifiable and the build quality is guaranteed. If you are considering a factory commission, speak to your finance provider early in the process.
You can, but the process can prove more complex. The vehicle will need to be independently valued (taking the modifications into account), and a specialist inspection may be required. Some lenders will not fund heavily modified vehicles at all; others will, but against a conservative valuation.
At Elev8 Finance, we work with a panel of specialist lenders experienced in non-standard vehicles. Get in touch to discuss your specific situation.
The examples that achieve exceptional prices at auction (such as the Koenigsegg CCXR Trevita or factory Hermès-collaboration Bugatti) share a common characteristic: they were created or authorised by the manufacturer, are supported by full documentation, and exist in genuinely limited numbers.
Private aftermarket customisations, however expensive, rarely replicate these conditions and should not be expected to perform in the same way at resale.
We recommend you commission a specialist pre-purchase inspection from an independent expert familiar with the marque. Request the full modification history, including receipts, the identity of any modifiers used, and confirmation of which (if any) modifications have manufacturer or dealer endorsement. Be sure to check whether the factory warranty remains in place and verify that the modifications have been declared to the vehicle's insurer.
Finally, speak to a specialist finance provider (such as here at Elev8 Finance) before completing the purchase, to ensure any finance is structured correctly around the vehicle's true market value.
