2006 Mercedes with 63,711 miles and has had all recommended service performed at the suggested mileage, including regular oil changes every 4,000 miles (synthetic oil). Car stalled without warning. Towed to Park Place Mercedes where it was diagnosed that pistons in cylinders 1 and 4 had come apart, requiring a complete engine block replacement. The cost of repair was quoted at $15,000.00. The value of the car, prior to the catastrophic event, as listed on Kelley Blue Book is $17,000.00 private sale. My expectation is that an engine on a well-maintained, vehicle should last beyond 63,711 miles, unless there are issues with quality of parts used, or the quality of the engine construction.
This car has been an ongoing nightmare since I have purchased it. The transmission has failed three times along with many electronics, engine components, water pump, oil pump, suspension three times, shocks twice, buttons, switches, wheel bearings etc.. This is nowhere near the build quality of any prior merceds I have owned. The tow truck has been such a regular to my street that the neighbors already know him. My kids scream when I attempt to dive it to take one of our other cars as they re scared to be in it and will break down again. This is the last Mercedes I will ever own. The mechanic at mercdes even told me that the cars are just terrible in the last few years. Stay far away!
I bought my 2006 R Class brand new in January of 2006. I have enjoyed driving the car and agree it has been the best car that fits my lifestyle, children, and hauling. However, this car has been very expensive to maintain. I have invested nearly $15K in repairs for things that were not covered under warranty. I have had to replace both the front right and left struts for $4K. The SOS system which I never used for $1,700. The seals on the transfer case for $1,100. The Cam Shaft for $5K. The airshock suspension systems for $2,100. The list goes on and on. MB USA has never stepped up to assist in any of these repairs. I doubt that I will ever buy another MB again. Don't love the car that much.
All cars seat the driver well, and most seat the front passenger well, but I know of no other vehicle that seats 4 or 5 more passengers behind the front seat in equal comfort. The middle two seats are large and spacious, think Business Class on an airplane. And even the two rear seats are very adequate for adults less than 6'2". With the glass Panorama roof you don't feel boxed in riding in an R-class.
Just bought this car in March '13. The car is a 2006 with 68K miles. During the test drive everything was running smooth and we fell in love with the car, (more the interior than the exterior) The car almost looks like a Minivan but it grows on you. After 3 months of driving this used car the Transmission pooped out on us. It cost $1,500 to fix and we did not take it to the dealer (this was the cheaper mechanic option) Now the car randomly drops the left side suspension. Apparently the air shocks deflate overnight or while parked for a long time and it tilts to one side. Can't wait to find out how much new air shocks will cost but I'm assuming it will not be cheap. Gas guzzler too!
