THE second-generation Mercedes-Benz SLK has already proved it’s not to be taken lightly as a serious sports convertible. The chassis is unquestionably more than capable, the interior is comfortable, relatively spacious and well thought out – and it doubles up as a snug, metal-top coupe or an open sports two-seater. With a genuinely useable boot. Add a 5.5-litre V8, set the suspension into a more aggressive mode, muscle up the braking system and you have an SLK with more than a touch of animal in it. Enter the SLK55 AMG – perhaps the most desirable of the entire AMG lineup available in Australia, and finally one of the most accessible ... if you call a two-seat car tagged at more than $160,000 accessible.
