When you're relatively wealthy and you have a knack for high-performance exotic sports cars, you buy a Lamborghini. And when you're utterly, fantastically rich beyond most people's wildest dreams? Then, you politely ask Lamborghini to build you something special.

That's how we come to have cars like this: the one-of-one Lamborghini SC20, revealed just last week as the second one-off build from Lamborghini's Squadra Corse, or "Race Team". It was designed for one especially well-to-do customer by Lamborghini's Centro Stile in Sant'Agata Bolognese, with heavy involvement from the customer, and in a new video, we actually get to see it get shaken down at Italy's world-famous Monza race track.

At few points does it seem like the driver is truly going flat-out during the test, which makes sense given the car's status as a high-priced one-of-a-kind customer car, but we still get to hear plenty of delicious crackles and pops from the exhaust on downshifts, not to mention its trademark Lamborghini V12 growl.

The SC20 borrows its powertrain from the Lamborghini Aventador SVJ, coupling its high-revving, power-dense 6.5-liter V12 with all-wheel drive through a fast-shifting seven-speed single-clutch automatic transmission. The engine, mounted behind the driver as on any proper Lamborghini, is good for a mighty 759 horsepower and 539 lb-ft of torque.

Arguably better than how it sounds is the way the Lamborghini SC20 looks tackling Monza's historic corners. The styling is truly unique, taking inspiration from some of the most striking Lamborghinis in recent memory and blending them all together into something aggressive and wedge-shaped, and yet at the same time, somehow delicate. It might be the first properly pretty Lamborghini we've seen in a while; seeing it in motion around a track, where we have a better sense of its scale, only reinforces our belief that it could preview the next-generation Aventador.

So, what would it cost to build your own Lamborghini SC20? It's hard to say; the automaker hasn't disclosed how much money its wealthy customer threw at them to build the very special one-off sports car. If we had to guess, we'd say it was probably somewhere north of $5 million. You might be better off with a Fiero, some fiberglass, and a sawzall.
