The armrests come up on uk ebay every once in a while. If you do long drives, the mod is worth it. If you track the car or do shorter trips, not so much.I did the cupholder, radio bezel with buttons & the rear headrests all in one order. In my mind, I couldn't justify the armrest cost for the small gain in function so I didn't do that piece. But the rest, I love love love the look & function. The euro radio bezel just looks so much more clean & sleek, & matches the rest of the interior so much better IMO. Plus the ability to easily turn off the display with the touch of a button is awesome. In addition to the better look, the rear head rests open up much improved visibility out of the rear window, it's like night & day. And the cupholder just looks sleek & clean. Those 3 things transformed the interior for me.
