Normally, when you buy a car, it's because you want to drive it. On average, you'll probably drive it about 15,000 miles per year. That means it's safe to assume a car from 2005 will have something like 180,000 miles on it. But hasn't been driven anywhere close to that much. In fact, it's barely been driven at all.
Currently , this GT has only 2.6 miles on the odometer. That's not far enough to have made it around the Nurburgring. Heck, people who are into jogging for whatever reason run further than that on a daily basis.
Essentially, this is a brand new Ford GT that's been preserved in its original condition since the day it was purchased. It's still got original plastic over the seats, the window sticker, and all the manufacturing decals. Whoever bought it clearly had it delivered, stuck it in the garage, and never touched it.
The only thing that hasn't been preserved about this car, however, is the price. Brand new, the Ford GT had an MSRP of less than $150,000. But 12 years later, it'll take $465,000 to own a brand new one. That's 2017 Ford GT money.
Then again, even if you have the money for a 2017 model, you can't actually go out and buy one. If you want, though, you can buy this Ford GT today. So maybe it is a good deal after all.
