Audi RS6 GT

Limited to just 660 examples worldwide, of which only 60 came to the UK, this is your opportunity to obtain the pinnacle of the Audi RS Avant family. The no-holds-barred farewell to Audi's lineage of fast wagons, the RS6 GT is far more than a set of wheels and some stickers, wearing the title of the most powerful combustion-engine production Audi there has ever been, with 621bhp on offer from its turbocharged V8 engine. Boasting a carbon-fibre bonnet and front wings, model-specific wheels, carbon-backed front bucket seats, 'RS Sports' height-adjustable coil-overs with adjustable damping, and a plethora of other upgrades exclusive to the hand-finished GT model, this is a true collector's item, and sold out almost immediately upon release.
