What's this Dell XPS 15 worth?

I'm looking for an estimate on this laptop—it's about two years old now, and the warranty has already run out. Any ideas?

I'm running Windows 8.1 64-bit right now—but I'm moving over to Windows 10.
It’s running a Windows 10 4th Gen Intel Core i7 paired with Intel Turbo Boost Technology 2.0.
It’s got a 15.6” screen—standard enough, I guess—but at least it features a Dell UltraSharp Display with that Full HD IPS tech and LED backlighting. It's running a 16:9 aspect ratio, which is pretty much what you'd expect these days.
A 1 TB hard drive.
It’s got that sleek, brushed silver aluminum finish—looks pretty sharp—paired with a black keyboard.
8,192 MB of DDR3L RAM running at 1,600 MHz.
NVIDIA GeForce GTX Graphics
Battery life tops out at around 4.5 hours—if you're running the PCMark 2012 benchmarks.
Weight: starts at about 4.8 lbs.
Dimensions: 14.8" x 9.6" x 1.06"

Thanks. 😉

It might be worth $3,000 on paper, but let’s be real—nobody is paying more than $667. It’s over two years old, the warranty is long gone, and anyone buying it is essentially taking a gamble without knowing what they're getting.
That said, if everything is running as smoothly as you claim, it sounds like an incredible machine; it’s a shame to see you part with it under these circumstances.

I'm with you on this. If you go looking for a new laptop, you won't find anything even remotely close to this quality, yet you'll end up paying a massive premium for it.
