For The folding hard-roofed Mercedes SLK is a sharp-looking, all-seasons roadster. It comes stuffed with luxury and safety kit.

Against The four-cylinder engines are coarse and noisy, and sloppy handling means the SLK isn’t much fun to drive. The dashboard is cluttered, too.

The Mercedes SLK is a nice enough car in its own right, but many manufacturers – such as Audi, BMW and Porsche – offer much better, more exciting roadsters for a similar price.

Buyer's notes

Target Price team says:

The Mercedes SLK range is reasonably simple. Petrol engines comprise two turbocharged 1.8s (badged 200 and 250) a 3.5-litre V6 (350) and a 5.5 V8 (55 AMG). There’s also a 2.1-litre diesel (250 CDI). The two 1.8 petrols are available with a six-speed manual gearbox or an optional seven-speed auto; the others get the auto ’box as standard.

Trim levels are standard or AMG Sport (the V8 is a stand-alone AMG model with its own look and equipment). The entry-level grade comes with alloys, Bluetooth, DAB radio and engine stop-start. AMG Sport versions add leather upholstery, a sporty bodykit, larger wheels and lower suspension, but they’re significantly more expensive than the standard models.

Despite the generous amount of comfort and safety equipment you get for the money, the options list is long and tempting. Pre-paid servicing plans are also available, as is a factory collection option where you fly to Germany to pick up your new car, then drive it home.
