Hello together, I am just exploring the R class market and have a question to which I have not yet been able to find an answer. Since we are “only” a family of 4 I am actually not looking for a 6 or 7 seater, but rather a long version with 5 seats. Since these are quite difficult to find, I slowly also consider buying a R class with retractable 3rd row of seats. However, I want to lose as little space as possible for this actually not needed extra. As far as I know, a long version with 5 seats has 633/2360 liters of trunk volume. My question, how much trunk volume has a long version with folded 3rd row of seats? Are there any other disadvantages of the 3rd row of seats?
