Back in 2007, Ferrari announced its Special Projects programme that gave their most prized and wealthy collectors the chance to create their own project. If you ever see 'SP' in the name of a Ferrari then you know where it came from.
Some of these one-offs were born through the programme, some weren't, but ultimately they're all special in their own way. Here's a list of some of the known, and maybe unknown models.
FERRARI SP12 EC
The SP12 EC is a one-off Ferrari made for Eric Clapton in celebration of his long history and loyalty with Ferrari and their products. Back in 2012 he teamed up with Pininfarina and mocked up a design for the SP12 which was then made into the real deal.
Based on the Ferrari 458 Italia, the SP12 features the same 4.5-litre V8 but has changed dramatically in terms of aesthetics. Taking heavy inspiration from the Boxer breed of Ferraris - the 365 GT4 BB and the BB 512 & 512i - Eric tried to bring the classic look, integrated with modern features, making it one of the most photogenic cars in the Ferrari lineup.
He spent $4.7 million to build his dream Ferrari which still remains in his possession and will be for the foreseeable future. When it comes around to being sold we can expect a much higher price than what it took to build.
Another car that saw the treatment of Pininfarina, this time for James Glickenhaus - heir to the Glickenhaus & Co. investment empire.
Approached by Italian design house Pininfarina in March 2005, James wanted a modern version of his classic 330 P3/4. Taking an unregistered Ferrari Enzo chassis, they incorporated a mash up between modern and classic, known as the Ferrari P4/5 by Pininfarina.
Revealed in 2006 at the Pebble Beach Concours d'Elégance, it instantly grabbed the attention of wealthy buyers that flooded him with offers. According to James, a member of the Saudi royal family offered him 10x what the car cost, equal to $40 million.
The Ferrari SP1 is a one-off special edition Ferrari based on an F430 for Japanese businessman Junichiro Hiramatsu, former president of the Ferrari Club of Japan. It's the first car that Ferrari's new Special Project programme attempted with many, many more following as the years went on.
Sources have it that Junichiro was a huge fan of the F100 - a concept car designed by Fioravanti back in 1998 which is where his inspiration comes from. As far as we're aware, nothing mechanical was changed, just aesthetics.
This one has seemed to attract less attention than others despite being the first of its kind. Unique? Yes. Attractive? Maybe.
Ferrari F12 TRS
Essentially a topless Ferrari F12, the TRS takes afflatus from the original 1957 250 Testa Rossa as requested by the owner. Making its first major appearance at the Goodwood Festival of Speed in 2014, it caused a lot of attention as it took part in the famous Goodwood hill climb and now sits in the small list of one-off customer requested Ferraris.
Engine wise the performance figures stay the same as its hard topped counterpart. The same 6.3-litre V12 engine resides within, pushing out 730bhp through the rear wheels, surrounded in 315 section tyres.
The luxurious interior has been stripped back to basics in aid of saving every bit of weight possible. Say goodbye to air conditioning, the entertainment system and even the glove box. Naturally carbon fibre and Alcantara litters the TRS's interior and exterior.
Ferrari F12 SP America
We've got another F12 here, this time with a less extreme transformation compared to the TRS, appointed by the CEO of Wegmans, Danny Wegman. Taking a look at it from a distance I can see design elements that look similar to the F12tdf and the GTC4 Lusso.
The body remains mostly the same with some cosmetic tweaks. At a glance it doesn't look massively different but once you delve into the changes a little more you'll start to see the smaller details.
The front end features an aggressive bonnet with extra cooling, revised splitter, carbon side skirts and various changes to the rear like a subtle spoiler, big diffuser and vents placed on the rear bumper that peel off to each side of the car.
Under the bonnet is the same 6.3-litre V12 which remains untouched. No actual figure has been released on how much the build cost but some rumours suggested in the region of £1.5 million to £2 million.
Ferrari P540 Superfast Aperta
This is the second car that was made through the Special Projects programme back in 2008 which was built for Edward Walson, the son of John Walson who created cable television. It's safe to say they have a little bit of money laying around so why not make your own Ferrari?
Built on a Ferrari 599 structure, the P540 is actually 20kg heavier than the standard car due to the chassis needing tweaking to accommodate the loss of the roof. Performance isn't affected by this extra weight and even if it did, it's worth it just to be able to hear that gorgeous V12 that little bit more.
The gold colour scheme is debatable but I respect that it's different.
Ferrari SP FFX Coupe 2014
Here's something a little different. At first glance it looks like a California but on closer inspection it appears to be an FF. Made for a buyer in Japan, the FFX is an odd one - I'm still not sure on if I like it or not.
The FFX is based on the Ferrari FF but the rear end has been completely redesigned to feature a coupe tail. The front end is more aggressive with two vertical sections that separate the grille, making it easier to distinguish what it is.
I guess the easiest way to sum it up is as the love child of a California and the FF.
Ferrari SP Arya
Special Projects came to the rescue when Cheerag Ayra, an Indian businessman, wanted to create his dream Ferrari. Housing a whole fleet of other prancing horses like his 599XX, this one will fit in just fine in the stable.
Multiple designs were sent to him for him to choose from. Not 100% happy with them he took various parts from each design which then birthed his new one-off Ferrari that's based upon a 599 GTO.
The fundamentals of the car remain the same, just with suspension and exhaust modifications at his request.
Ferrari Superamerica 45
New York real estate giant Peter Kalikow commissioned his own take on the perfect Ferrari to celebrate 45 years since his first purchase into the brand - a 1961 Ferrari 400 Superamerica.
The Superamerica 45 looks like it has taken massive inspiration from the Ferrari 599 SA Aperta that came out the year before this. Look a bit more closely and design elements from the 575 Superamerica start to show.
Starting from the front, it features a new chrome grille with revised air intakes on the front bumper. Moving towards the back of the car we can see colour coded wheels to match the Blue Antile paint colour that adorns the body, with chrome elements for contrast. A GTO style rear diffuser finishes off the rear, giving it that more aggressive look.
The biggest change being the one piece carbon roof which slots into the rear deck when removed. This is a one-off design that hasn't featured in any other Ferrari before.
Ferrari 458 MM Speciale
Moving onto the most modern car on the list we have the Ferrari 458 MM Speciale. Based on a, well, 458 Speciale, the MM was built for an undisclosed buyer in the UK.
Built to his specification, the MM has the same 4.5-litre V8 that produces 597bhp. The owner wanted a visor type effect which has been accomplished by painting the A pillars in black. Unsurprisingly the car is made almost entirely from carbon fibre, keeping weight to a minimum.
With the revised air intakes on the side of the car that lead to the radiators, the MM almost looks like a Lotus Evora - in my eyes anyway. The rear now shares features with the 488 GTB and is adorned in a Bianco Italia paintwork with traditional Italian racing stripes.
