I have a 2005 MB S 430, Granted it stays in a heated garage and is cleaned all the time.. I have had no problems with this car at all 130,000 miles. Just brakes and tires, reg oil changes. The only part I have replaced is a heater control valve in the cowl area, $175.00. no big deal. The car is adult driven and yes I did buy this car new. Going on a trip this summer and I am planning on replacing the Belt before going.(age)
Not what it should be. Over rated. Too costly for every little service. Floor mats are not good....they should be attached to the floor so they do not move. The AC is not very strong ( I live in Flporida) takes too long to cool the cab. I do not like the windshield wipers, with it auto wipe on rainy days. There are a lot more problems........... for the price ......it sucks.
