You can look at it from a different prospective: this truck only has 73kmi on the clock, easily has 150-200k more to go.
If you take a third off the price of a 4-door JK/JL (which are not much more capable in stock form and definitely less comfortable), $14k for a clean D1 is not a bad deal.
I'd have one of the good indie shops around Phoenix fine tooth comb it.
If it passes muster, then considering all the unobtainium Safari Gard parts, ARB Lockers front and rear, the wiring and tube routing involved, and relatively dry undercarriage, that's a fair deal. Not great, but fair.
Check for any corrosion, esp. at all the grounds. They need to be without corruption for a LR to function properly.
Thanks for the reply. I had a shop look at it today and the key takeaways were all routine; the front diff and engine oil should be changed, the rear brakes are worn, and the tires are six years old. Otherwise it's looking like a fair deal and I'm leaning towards pulling the trigger.
