Another fun option is removing all your plastic interior trim. The body color paint is under those plastic trim pieces. Removal gives a nice utility look. As far as working with ABS, it's super easy. If you need to modify it to fit around the wiring harness or jack mount, just heat with a heat gun and form it to the shape. Once cooled it'll look OEM. If your not keeping the rear washer or jack, that space can be modified to accommodate storage, compressor or inverter. I've had my panels in for almost ten years and they're still rock solid. No discoloration, deformities or rattle.
Good luck!
