What Car? says

4 out of 5 stars

For Sublime refinement; effortlessly classy

Against Running costs are steep

Verdict It’s big, imposing and worth the money

Go for… S320 CDI

Avoid… S5000

Mercedes-Benz S-Class Saloon
  • 1. The S-Class is luxurious, refined and epitomises what luxury cars are all about
  • 2. The S-Class also comes packed with technology designed to keep passengers safe and the driver in control
  • 3. The 320CDI diesel version makes the most sense, with more manageable fuel bills and better resale values
  • 4. The electrics are the most vulnerable with the Comand sat-nav system a possible weak spot, while the engine can slip into safe mode and require dealer attention
  • 5. Ex-limo and executive taxi cars are easily spotted – thanks to their astronomical mileages – and are best avoided
  • 6. The 320 CDI diesel does an average of 34mpg, which isn't bad considering the size of the car, but road tax will cost over £400, because of the CO2 emissions of 220g/km
