For A 5.5-litre twin-turbo V8 takes pride of place in the S63 where once there was a 6.2 V8. Performance junkies needn’t fear, though – it’s still monstrously fast, but with greater driveability and reduced fuel consumption and CO2.

Against Running costs and depreciation will be huge despite the improved efficiency, but that won’t be the clincher for people spending a six-figure sum.

A connoisseur’s choice because of what it costs to buy and run, but if you’re lucky enough to be able to afford one, it’s a superb high-performance saloon.

The full Mercedes-Benz S-Class Saloon S63L AMG review


Buyer's notes

Target Price team says:

You could certainly argue that, pound for pound, the Mercedes S-Class is the best car in the world. Whatever you want from a luxury car, the big Merc does it - and does it very well.

There is a wide range of engines, our favourite of which is the smooth and powerful diesel V6. Unless you'll be the back-seat passenger or are planning to be a chauffeur, don't bother with the more expensive long-wheelbase model, though.

On top of the three-year unlimited-mileage warranty, Mercedes cars also come with the Mobilo breakdown assistance package that provides you with assistance on the road for up to 30 years in more than 30 European countries. Different benefits apply, depending on what the problem is, and full details are available from the Mercedes Customer Assistance Centre.

My S63 AMG four-door is so fast and the handling is so great that 10 days later I brought another four S320s.
