Measuring just under five metres in length, the R-Class already demonstrates its superb all-round qualities. But if you want more, opt for the long-wheelbase version, which is 23.5 centimetres longer. It has many advantages: with six or seven people on board, for example, the passengers in the second and third rows will enjoy greater legroom comfort. And even with the third seat row the luggage compartment still offers even more room for your belongings – 414 litres of load capacity up to the roof, to be precise. The R 300 is only available as a long-wheelbase version.
