The level of detail is absurd. You can choose leather, Alcantara, or (a Koenigsegg-exclusive wool blend from Norway). You can color the seat belts, the contrast stitching, the piping, and even the anodized aluminum dials on the steering wheel.

You choose the primary finish, the secondary finish, the center lock color, and even whether you want the aero carbon discs behind the spokes. Do you want gold with a polished lip? Or murdered-out matte black with red accents? The engine isn't the only thing spinning here. Click "Interior." Prepare to weep.

It’s therapy. It’s torture. It’s art. Does the Koenigsegg Jesko configurator help you buy a car? No. Does it help you appreciate the engineering madness of Christian von Koenigsegg? Absolutely.

There is a specific option called "Gearshift Paddles in Machined Solid Aluminum." Not plastic. Not carbon fiber. Solid machined aluminum. Because when you shift gears in a 1,600-hp car, you want to hear a clink . The best part of the configurator is that it isn't a "render." It is a 3D, ray-traced, photorealistic simulation. You can spin the car around, open the "Autoskin" doors (hydraulic doors that pop out and forward), and look at the 5.0-liter twin-turbo V8 through the rear glass.

You aren't just picking paint; you are picking exposed carbon fiber weaves. Do you want (the standard twill), Diamond Dust (sparkly), or the utterly unhinged Vortex (which creates a 3D optical illusion)?
