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.
Interrior, 3rd Row, Captains Chairs, Sunroof, etc.
Maintenance and Repairs are way above average. More Major system issues after warranty expires than any of the 15 vehicles I have own previously.
