I've been looking for a Ford Powerstroke for a while. I seen one online and I'm wondering what it might be worth. It's a 06 F250 extended cab xlt. Has 87k miles. No accidents. It says it's fully built. All the stuff done to it was done 4000 miles ago.

-Heads were resurfaced and new OEM headgaskets with Elite Diesel Engineering H11 studs.
-GOGO diesel hd valve springs and shims with HD pushrods.
-Oil cooler replaced with one updated from Ford.
-Sinister full EGR delete
-64mm stage 2 turbo
-Sinister return style fuel system.
-Airdog II
-TSD sump
-CFM large mouth intake elbow and side pipe
-Coolant filtration kit
-Custom Gearhead Automotive tunes
-Pyro, trans, fuel pressure, and boost gauges
-Updated STC fittings
-4 inch down pipe, 5 inch exhaust
-Leveling kit

So what would be a good price for it?
