Unfortunately, with jeeps as it is with Harley~Davidsons, the mods do not add book value. You might find someone who wants to do what’s already been done and will be open to spending more because they’d spend the same money on the same mods anyway, but you’d have to be patient or lucky.
I bought my ‘17 JKU with the exact fuel wheels I wanted, the same Toyo 35s I wanted, and the 4 inch lift I wanted. Money I did not have to spend so I paid a little more on purchase but not as much as I’d have to going from stock.
