Finding an unmodified 13yo Jeep is a tall order, your search is further hampered by the fact that the Islander is an appearance package and may not come up on search terms.
I did find one but I think the mileage will be a real issue.
The bumpers are easily found to restore it to original and this one looks like it lost the decals along the way.

Curious, why this particular package?
