Heavily modified Lamborghinis aren’t particularly rare these days, and for those looking to boost the performance of their Raging Bulls, throwing on a pair of turbochargers is, probably, the first thing that comes to mind.

However, while twin-turbo’d Lamborghinis are quite common, we’re willing to bet you haven’t seen a twin-supercharged Lamborghini like this one before.

It is a first-generation Murcielago which has been fitted with a number of LP640 parts and a plethora of aftermarket mods across both the exterior and interior. But let’s start with the engine, shall we?

The car is currently located in Amsterdam in the Netherlands and the listing, apart from the €750k ($835k) asking price states that it pumps out 935 PS (922 hp) from its supercharged 6.2-liter V12. Other modifications include aftermarket pistons and connecting rods as well as an exhaust system with adjustable butterfly valves.

This Lambo was created by a small tuning company dubbed ESV out of Germany and is officially dubbed the Seponas LM900. Only one unit example is believed to have been built and the car is clad in carbon fiber body panels. Also found across the exterior are custom wheels and headlights inspired by those from the Lamborghini Reventon.

If you thought the exterior was crazy, you’ll likely be shocked at what’s going on inside. Much of the cabin is clad in bright blue Alcantara that is contrasted by white leather on parts of the door panels, steering wheel, the lower half of the dashboard, and the seats.
