I think the Swamp Police SUV in 60068 is one of the best out-of-the-box minifig scale offroad vehicles Lego has ever designed, looks-wise. It's a marriage of a Land Rover Defender and Dodge Ram with a lifted Jeep's proportions.
I took the design and pushed it just a little more. I was inspired by the US Forest Service's and Border Patrol's paint schemes, as well as then open-sides look of the Jeep Wrangler Hardtop Concept:
My mod is probably 95% similar to the original model. The front end has been played with, giving it a contemporary LED-style light bar in place of the original model's four round lights, and a winch in place of the original bumper's tow hook. The headlights and grille are more generic (or perhaps closer to classic Nissan/Suzuki shapes). Aside from the obvious replacement of the rear windows, the rear is identical to the original build. The roof rack was an interesting sketch that plays out beautifully.
I will be making this for real at some point soon, I have near total confidence that all the dark green elements exist. I'm torn on which windshield to use though. Any thoughts?
