The B7-generation Audi RS4 arrived at a particularly memorable point in the development of the German performance car, an era when high-revving, naturally aspirated engines still ruled the roost.

At its heart was Audi's remarkable 4.2-litre V8, producing 414bhp and 317lb.ft of torque, driving all four wheels through the marque's quattro system and, importantly, a six-speed manual gearbox. Whilst the RS4 was perhaps best known in Avant form, the Cabriolet offered much the same formidable performance with the added appeal of open-air motoring.

With its subtly muscular bodywork, flared wheelarches, large oval exhaust outlets and discreet RS detailing, it remains an impressively purposeful-looking motor car without being overly ostentatious. Supplied new by Eastbourne Audi in 2006 at a cost of £63,873, this example is finished in Phantom Black Pearl Effect with a black fabric hood over Silver Nappa leather, piped in black and complemented by carbon-fibre inlays.
