Start with the car that you've already got. In this case, Lamborghini's engineers started with the 700-horsepower Aventador LP700-4, leaving its 6.5-liter V-12 engine intact and untouched. View Local Inventory

Next, grab a Sawzall and hack the top off...or have your team of industrial designers engineer an open-top variant, whichever method is easier for you. View Local Inventory

Normally, this is the point where you'll add some sort of retractable top, call the car a "concept," and trot your new model out at the next major car show wearing a coat of your fanciest paint. View Local Inventory

And if that weren't mad enough, Lamborghini's designers also hacked off the windshield, necessitating a closed-faced helmet if you plan on coming close to the supercar's 217-mph top speed without a mouthful of bugs. View Local Inventory

Okay, so perhaps I'm oversimplifying the process. Lamborghini also made other changes to make the Aventador J look and feel cohesive. For example, the interior--if you can even call it that--features body-color matched paint. View Local Inventory

The rear end of the Aventador J is further optimized for cooling and aerodymanics. A quad-tipped exhaust likely makes a glorious noise. View Local Inventory

I didn't think it was possible, but the roofless Aventador J appears even more poised to pounce than the already low-slung standard model. View Local Inventory

Here's the twist: I haven't even gotten to the craziest part. Lamborghini ~~plans to sell~~ has already sold this one-off example of the Aventator J for about 2.1 million euros. View Local Inventory
