Ollie Marriage from Top Gear Magazine got his hands on the Factory’s demo 4R (last seen with protective tape wrapped around its leading edges to ensure it remained in pristine condition for the TG photoshoot). You can read what Ollie thought of the 4R (all estimated £140,000 off it) here: https://www.topgear.com/car-reviews/ariel/atom-4r/first-drive but suffice to say, he rather liked it.
