The K1 Attack is from Slovakia, the Tushek Renovatio T500 is from Slovenia. The two countries don't share a border, but the two cars do share an origin: the T500 uses slightly redesigned bodywork from the K1 but is substantially reengineered underneath, one such example being the presence of a mid-mounted 450-horsepower Audi V8.
Autocar went to Slovenia to give it a spin and reviewer Matt Prior liked it, praising its engine response, chassis engineering, fit-and-finish and huge options list. In fact, for the company's first effort, it sounds remarkably polished and well-engineered. The biggest hurdle the open-top T500 could have to jump is its own price: at £300,000 (around $467,000), it's more expensive than the £195,500 McLaren MP4-12C Spider (around $300k), and its price exceeds that of the €255,000 Lamborghini Aventador ($400k) and the predicted €274,000 price of the Ferrari F12 Berlinetta (circa $425k).
But we're told two have already been ordered and paid for, and the Tushek folks make no claims about wanting to take over the world, planning to build just 30 over the next four years. Yet if that's the bar for the T500, we can only wonder what the Tushek Forego T700 is will be charged with. You can checkout Prior's T500 review in the video below.
