2007 Ariel Atom 3

A 2007 Ariel Atom 3 finished in the rare Viola Parsifae hue — a Lamborghini-sourced purple that transforms the Atom's skeletal aluminium frame into something genuinely striking. This example has covered 18,000 miles and benefits from the factory-fitted 3.5 Light Upgrade, carried out by Ariel themselves, along with the £1,000 optional windscreen that turns the Atom from a full-helmet-only weapon into something usable on longer runs without blunting its directness.

Powered by the supercharged Honda-sourced 2.0-litre K20 four-cylinder mounted behind the driver, the Atom 3 weighs around 500kg and delivers a power-to-weight ratio that rewrites the driver's expectations of acceleration. The exposed tubular chassis, inboard pushrod suspension and total absence of bodywork place this firmly in the track-toy category, yet the windscreen and road-going spec make it a credible B-road tool. Finished in red with the trademark Viola Parsifae accents, two seats, and presented with meticulous maintenance, this is one of the more distinctive Atoms to come to market.
