Itay1988 - I'm also new to the forum but have been lurking since the end of 2020 when I picked up my 2016 PIU (a former Washington state patrol PIU). I purchased my custom floor mats from Nenno Products and have been very happy with them (as well as the black spotlight hole sticker/cover). I also added an aftermarket center console, auto headlights (requires a light sensor, new switch, and ForScan), a couple of ham radio antennas and radios that switch from the 4-switch steering wheel controls, rear doors that open from the inside, rear speakers that aren't actually closed in the door panel, 2nd row headrests, pet cover for the cargo area, a rear tailgate that unlocks with the rest of the car, tow hitch, and bolted on Yakima roof rack. Still a few more mods in the works for me but here is the link to the carpets I've been happy with:
They are specifically engineered for vinyl / rubber floor mat police vehicles that were built without carpeting. They are a most welcome civilian touch to the interior of your interceptor and add another element of sound absorption.
