Servus with each other! I will probably have to get a new used car in the near future. I put a lot of value on the long-distance comfort, because I have to travel long motorway routes due to my service (about 20,000-30,000km per year depending on the location). Furthermore, I need space, lots of space, and in view of my personal wish- family planning, this would be the right space for a R class. I have already looked at the GL, but here fails. My questions: – Is it possible to upgrade the R 500 L with 388hp to LPG or LPG or LPG? – Can the third row of seats be lowered as elegantly as with GL, so that a flat loading area is available? – Did you have any problems with parking spaces, especially underground garage entrances? – Can you retrofit a rear camera? If so, what would that cost about? – I read here in the forum that it is supposed to rattle like in the R. Well, wi r have a vaneo in the family and there it is really terrible… I feel less like it, especially on long sticks. – What should you pay special attention to when buying used goods at the R? – Can you give me a clue about maintenance (inspection, brakes,…)? Thank you for your answers! Greetings, Tobias
