When it comes to restyling interiors, Vilner Studio is one of the few companies creating high-quality cabins on a consistent basis for an array of different vehicles. Based in Bulgaria, the aftermarket specialist is just as comfortable decking out Japanese sports cars like the Nissan GT-R as it is creating new living spaces for German super sedans and SUVs. If you like to see how a master craftsman makes a plush interior even plusher, continue reading, as what follows are five of the best Vilner interiors on the market.

When tackling the ever-popular V10-powered, E60-generation BMW M5, Vilner added a set of satin black HRE P40 Series alloys before reworking the cabin. The Sofia-based outfit fitted an Alcantara headliner and used leather to trim the steering wheel, handbrake, seats and door panel. The leather is perforated for a sporty look and top-stitched in red and blue for the complete M look. Carbon-fiber elements on the dash, center console and doors complete the stylish makeover. There's no word on price, so interested parties are advised to contact the firm directly.

When a client "wanted a non-standardized execution of his racer," Vilner used the Year of the Dragon for inspiration with the mythical beast acting as motif and red dragons tattooed on the headliner and Alcantara-coated trunk of the Nissan GT-R. Red embroidery and seams on the dashboard represent the body of the dragon winding around the seats and across the center console. Vilner used carbon fiber for the steering wheel and gear shifter with the more intricate details painted in red chrome. Black Alcantara and black leather adorn the dashboard, door panels and console, while the rest of the cabin is upholstered in quited leather with suede accents.

After wrapping this Audi S5 in matte grey and adding a new radiator grille, trunk spoiler, diffuser and alloys finished in gloss black, Vilner turned its attention to the cabin, upholstering every inch in black and brown leather with Alcantara. The seats are covered in leather with diamond stitching used on the base and shoulders, and black Alcantara on the bases. The micro-suede material also covers the roof headliner, pillars, rear-view mirror and dashboard, while a strip of contrasting black leather runs the length of the rooflining and along the rear seats. As a final flourish, the customer's initials have been stitched into the front headrests, considerably restricting the list of potential buyers if the owner ever wants to sell.

Vilner lavished the Mercedes-Benz GL with some serious interior styling, starting with the big SUV's seating arrangement, replacing the rear bench with two individual bucket seats. Through the middle of the GL, the design crew has added an extended center console complete with aluminum trim, cup holders and an integrated iPad. Vilner fitted a new headliner made out of a light-brown Alcantara, complimenting the black leather seats and door panels and bathed in ambient lighting. The entire cabin is also lined in Ground Zero soundproof material for a quieter ride and better acoustics for the sound system, which packs two subwoofers, three amplifiers, and is controlled from the iPad.

Fianlly, Vilner offered two contrasting packages when revamping the interior of the S63 AMG. The first conversion can be described as modern-retro featuring tan leather seats with matching trim on the doors, roof and A-pillars, while the second is more sophisticated, blending black and white throughout the interior. Alcantara, Nappa leather, mahogany wood and black & white piano lacquer are the materials of choice in these modifications, with no hint of plastic remaining.
