This year's SEMA show in Las Vegas treated us to a plethora of modified Mustangs with upgraded powertrains and brash body kits. European styling house Vilner Garage has taken a different approach, however, by revamping the interior of a couple of 2015 Mustang GT Convertibles.

They're both suitably lavish - you won't find any cheap plastic materials in these plush Mustangs. Also, if you've never heard of Vilner before it's the same company that added real horse hair to the seats of a Mustang for a Chinese client.

"Of course, there is an obvious reason for us showing you two projects based on the same model, side by side. It's a showcase of our different stages of personalization," company boss Atanas Vilner said.

The first Mustang finished in blue features a black leather dashboard with contrasting white stitching and cobalt-colored Alcantara to match the exterior. The blue and black theme has been applied to most of the interior including the door panels.

The other convertible Mustang finished in blue with white stripes has a more eye-catching interior thanks to its tri-color red, white, and black color scheme. The door panels and seats feature contrasting strips in these shades, including white stitching, while the dashboard and the center stack is finished in black and red.

Both cars also feature custom steering wheels with two types of leather for the ring and an embroidered Mustang logo galloping on the door covers and carpets. According to Vilner, the extensive use of Alcantara and leather materials cover up all the "scratchy plastic" parts the Mustang is often criticized for.

The car's 5.0-liter V8 engine has been left stock, so it still delivers 435 hp and 400 lb-ft of torque, and the exterior has also been left untouched apart from the addition of a discrete Vilner badge at the back.
