well, they "invested $40K"!
more like set fire to $40k. I'd redo a lot of it....found a nicer proper four door in WA that just sold for the same $$$ so just goes to show what patience brings.
as with a decision a decade ago to buy a new Wrangler vice an 8yo D90, one would be hard-pressed to buy used British or German for the same money as a new JK, if logic and fiscal responsibility enter your equation. That's always the conundrum; "cool" is trumped by not wanting to buy a money-pit.
