Need help with excursion purchase decision
The 6.0 is really nothing to be afraid of, the big thing is keeping up on maintenance:
-Fresh Oil
-Clean Fuel
-Motorcraft Filters
Keep things changed at the proper intervals and you won't have a thing to worry about.
Some things to lookout for (you'll need an AE or some kind of scantool):
-If you see green coolant in the degas resevoir, there are two ways you can go about it:
1. Thank them for their time and walk away.
2. Hook up a scan tool and monitor the Engine Oil Temp and the Engine Coolant temp, with the engine fully warmed up and cruising at 65, see what the delta is...I believe if the delta is higher than 11 degrees then you may have clogged or clogging oil cooler than will need some attention.
I say all this becuase green coolant has no place in the 6.0 due to the silicate dropout that causes the oil cooler to clog, causing a deadly (and expensive) chain reaction.
If you have healthy deltas (less than 11 degrees between EOT and ECT)Have them flush the coolant and replace with an ELC like Rotella or CAT.
-Check the degas cap and make sure you don't see any type of hard baked on coolant. If you see that, it may either need a new cap or it may have a headgasket problem. However with only 40K, I don't see that being a problem.
-Take note of how the truck starts cold. If it starts rough and won't idle smoothly, the FICM or Fuel Injection Control Module may need some attention or you may have an injector or two that needs replacing.
-Look on the passenger side valve cover and see if the sticker either says 2004 or 2005. If it's a 2004 engine, disregard, but If it's a 2005 drive the truck until hot, shut it off, wait a few minutes, and restart. If the truck stuggles to restart or takes a little longer than usual to crank, it may have a high pressure oil problem. Dummy plugs, STC fitting, or Standpipes may need to be replaced.
Other than that, drive the truck and you'll know what needs attention. The above is what I would look for being experienced with the 6.0.
As you can see from my signature line, I have done a few mods, but the X has been great and I haven't had a single problem with the 6.0.
My advice is to take a close look at it (crawl under it) and if it is really the vehicle you are looking for, go for it.
It also takes at least a 10 mile run down the highway at 60 to 65 mph for the oil to get to temp. fwiw
Good luck
2005 FORD EXCURSION DIESEL 4X4 <--20K
2005 Ford Excursion Diesel 4x4 <--$18.5K
2005 Ford Excursion - Limited - Turbo Diesel <--$16k
2005 Ford Excursion Diesel 4x4 <--$19.5
I'd even consider those I've posted as mildly overpriced since I've seen a few of them in the $13-15K range over the past few months.

He shouldn't be afraid to make a low offer. When I bought my Excursion I offered and got a price that was thousands lower than what the asking price and KBB was. Fortunately it was owned by a non-profit that rarely used it and had zero emotional attachment to it (and it's a gasser).
I'm a DIY mechanic with decent skills and know that if you gave me a $10K 2005 Excursion with 200K miles, I could spend another $20K and have a MUCH better truck than a $30K 2005 that only had 40K miles. For that kind of money I could either upgrade or bulletproof the engine, install a HD trans, loaded interior, new suspension, wheels/tires, paint, etc.
Since the components in these trucks usually run 400K (not always the 6.0 but you know what I mean) without anything major, it's relatively safe to say that you wouldn't have to replace every major component on the truck but even if you did, you'd still come out cheaper and have components with 0 miles on them instead of 40K.
I'm biased because I came from a background of finding the vehicle you wanted with a straight body and blown mechanical parts, and then replacing the mechanical parts and ending up with a "newer" car than what you could have bought if you found one in perfect condition. OR buying a vehicle with higher mileage for a significantly lower price knowing that if major components failed, you'd still come out cheaper than having bought a lower mileage vehicle.
