Supercars and hypercars come up for sale all the time, and some are rarer than others. But every once in a while, we come across something truly unique. And that’s just what we have here.

What you’re looking at is the 1999 Sbarro Espace GT1, a one-of-a-kind supercar made by one of the industry’s more creative designers.

It’s Sbarro’s take on the the Mercedes-Benz CLK GTR, a rare homologation special of which fewer than 40 examples were made by AMG and its racing partner HWA. As rare as that leaves the CLK GTR, the custom coachwork fitted to this show car make it stand out even further.

At the heart of the Espace GT1 sits a massive 7.4-liter V8 engine, instead of the 6.9-liter V12 fitted to the road-going CLK GTR or the 7.3-liter V12 that powered the racing version. Mounted amidships, it sends 450 horsepower to the rear wheels through a five-speed sequential gearbox. And weighing in at less than 3,000 pounds (1,350 kilograms), it’s said to be capable of reaching 62 mph (100 km/h) in 4.9 seconds before topping out at 202 mph (325 km/h). Hardly mind-blowing figures by today’s standards, but certainly no slouch for the late 1990s, when even the Porsche 911 Turbo packed 402 hp, and even the hyper-exotic Ferrari F50 boasted “only” 513 hp.

Franco Sbarro and company revealed the Espace GT1 at the 1999 Geneva Motor Show and sold it right off the show stand. Now nearly 20 years later, Magna Supercars out of Marbella, Spain, has it listed for sale on JamesEdition with 876 miles (1,410 kilometers) on the clock. The dealer hasn’t disclosed how much it’s asking for the one-of-a-kind supercar concept, but you can bet that its unique status and radical styling will result in a suitably high price tag measured in the seven-figure range.
