When you think of Porsche, it's the 911 that comes to mind. The consummate sports car may be the brand's finest achievement, but it's certainly not the most incredible. Over the years, the Zuffenhausen-based automaker has spewed out some truly glorious motorcars. The most recent halo model is the 918 Spyder, a hybrid roadster built to rival the LaFerrari. In the '80s, the Porsche 959 filled that role. But in between, is perhaps the brand's most revered car of all time.

First seen in 2004, the Carrera GT was designed to give the McLaren Mercedes SLR and Ferrari Enzo nightmares. Powered by a 5.7-liter V10, the mighty German has 605 horsepower at its disposal. Mated to a six-speed manual gearbox, it's often described as one of the world's greatest driver's cars. Yet the owner of the pristine example you see below has covered a mere 27 miles in 18 years.

Offered for sale on DuPont Registry, the Metallic Silver example boasts extremely low mileage. Most likely bought as an investment, this $3.5 million supercar is about to yield some impressive returns when you consider the original $450,000 price tag. This is one of the earlier cars, with an inscription on the dashboard showing it as the 154th model out of 1,270 ever made.

The interior presents as new, with gorgeous Terracotta leather and interior trim. The gear stick juts out of the center console, with the signature beech wood-trimmed knob teaming well with the carbon fiber and metalized trim. The plush innards may suggest luxury, but the Carrera GT is an unforgiving supercar. Every single component was designed with efficiency in mind. The body panels and tub, for example, are made of carbon fiber. Even the wheels are made of forged magnesium to keep the weight down.

$3.5 million is an incredible amount of money for a car. But the rarity, reputation, and sheer desirability of the Carrera GT justify the price. Add to that the very low mileage (delivery miles, essentially) and it may just pique the interest of several collectors with deep pockets. An example with 182 miles on the clock is heading to the auction block later this month and it will be interesting to see what kind of money it commands.

Before these low milers, a Carrera GT with 2,700 miles on the odometer sold for more than $1 million. Ultimately, it still has very low mileage and we're not sure the example seen here is worth an additional $2.5 million. Then again, these are the things some collectors look for, so the extra outlay may be worth it for the right person. As a car designed to bring joy, it is rather sad that it has barely been driven. We certainly hope its new owner adds many miles to this gorgeous example.
