"We wanted to launch the Specialist Products Division with something unique – and the DR 520 fits the bill perfectly.  Mercedes-Benz World is located at Brooklands, and there's a proud history of ‘Brooklands Specials' being sold here over the years.  The DR 520 – which is dyno-rated at 520 hp - is our chance to create an exclusive model in the UK.  It's a great opportunity for us to offer our customers who enjoy sports and supercars a bespoke car with even more performance than the already very successful C 63 AMG.  And as well as the increased performance, it looks incredible, too.", commets Nigel Unsworth, Specialist Products Division Manager.

The DR 520 is only £9 995 above the standard C 63 AMG, so the Saloon is perfect value for money - £62 430 OTR and the Estate £63 680 OTR.

Of course, the cars are covered by a three-year, 60 000 mileage warranty.
