BRILLIANT performance, exceptional handling. Those accolades are heaped on all sorts of motoring dross these days, but they are words that actually mean what they say when applied to the Mercedes-Benz C63. The smallest Mercedes-AMG model is a heavily breathed-over C-class, with the kind of performance that will make your eyes water and an engine note that will make anyone who loves cars weak at the knees. Its appearance may suggest it is little more than a warmed-over executive sedan covered in a plain wrapper, but look beyond the exterior and consider it is motivated by a fire-breathing 6.2-litre V8, and you’ll find that this C-class certainly is no boiled lolly.
