The Porsche Carrera GT was born from an abandoned race car project, so it seems logical that it would be at home on track. And if you extend that logic further, a Porsche Carrera GT track car makes perfect sense. This is such a car. Dubbed the Carrera GT-R, it's a full-blown race car built from a Carrera GT, and it's up for sale with an asking price over $1 million.

Mechatronik, the German company selling the Carrera GT-R, says that this car was bought by a Belgian collector who immediately sent it to a firm called GPR Racing to turn it into a proper race car. GPR installed a Motec engine management system, new suspension components, AP Racing brakes, a roll cage, air jacks, and all the other kit you need in a race car. Amazingly, this car retains the Carrera GT's manual gearbox. Bonhams sold this car back in 2015, and since then, a livery aping the #25 911 GT1 that placed second at Le Mans in 1998 was applied. Apparently, this project cost around €220,000 ($270,000) to complete.The owner wanted to run this car in endurance races, but that never happened. Mechatronik says that because of Balance of Performance restrictions, it wasn't able to be homologated; Bonhams said that Porsche wouldn't allow it to race. Whatever the reason, the car was mostly unused, and today, it only has 2000 km on its odometer.

If you bought this car, you could be a big showoff and bring it to your local HPDE day, but more likely, you'll just hire the track for a private session. That's probably the most economical option, as replacement parts for a Carrera GT aren't cheap. It's hardly the most sensible track day car—for less money, a 911 GT2 RS Clubsport is likely quicker and easier to run—but that's not the point. Think about the sound, the sensation. Subjectively, this might be the best track-day car in the world.
