In the deep bunkers somewhere in northern Italy, swatches of the finest fabrics are sprawled across the table alongside spools of thread. This is probably the world’s most expensive tailor; but it isn’t Brioni or William Fioravanti. This is where the elite visit when they want something tailor-made for their Ferraris.

Sitting in the middle of the private studio is a 458 Spider. Apart from the blue and white stripes that run down the centre of the brilliant-red roadster, it probably looks like any other Ferrari to the untrained eye. The design is inspired by the historical 250 Testa Rossa that was sold at an auction for US$16.4 million (S$20.6 million) in 2011. The details continue inside, with an aluminium-clad interior and diamond-quilted fabrics that mimic the look of the 250. The seats are also upholstered in a chamois-like leather that is the exact same material that was used in Formula 1 cars of yore.

Owners who want to customise their Ferraris can go to the home of the Prancing Horse in Maranello to meet designers who can create one-off designs inspired by Ferrari’s rich history or racing heritage, or tap into a collection of different materials to create something new under its Inedita theme.

“We use materials that are used in other industries, such as boat-making and interior design,” says head of product marketing Nicola Boari. This isn’t the usual customisation programme where choices are limited to a palette of colours and a swatch of garden-variety hides. The options at Ferrari Tailor-Made are limited only by one’s creativity (or tastes), and to the car’s cosmetics.

“You can’t change the technical specifications because all Ferraris are already engineered to the best specifications possible,” Boari says. When asked about the most extreme example, he cites the FF model owned by golfer Ian Poulter, which has an interior clad in – you guessed it – his trademark tartan fabric.

But, in the rare case, the marque still has to put its foot down. Boari says: “Pink Ferraris are definitely not allowed.”
