"have a R500 looks good, rides good and has all the bells and whistles. Bought is used and the word USED I use loosely. The car has been in the shop at least once a month for as long as 2 1/2 weeks. I have already decided I will have to trade it before the Certification runs out or it will cost me a fortune. I dont think MB puts quality parts and features on this car as they do there other high end ones. Wish I would have bought a BMW and will next time."
"Bought the 2006 R-500 model in Nov 06. Loved the looks and the inerior was very spacious and comfortable. Very kid friendly with dual video monitors. The drive is very forgiving with a sporty feel to it. Very surprised on the great handling. Lots of power. A little more noisier road noise than I expected from a MB but not that bad. My complaints are that it has been a service nightmare. Have taken it to the shop atleast 4 times to fix the rear hatch (won't open-they keep adjusting or replacing the latch but I believe it is the hydraulics which cost more so they are trying everything else). The front and rear lights have had 3 faults so far. The driver side-view mirror motor just broke right after the 50000 mile warranty and they are telling me that it a $1400 motor. All together it has been in the shop atleast 8 different times not including the multiple scheduled services that come up. I expected a little better service record for a MB. I know it is the first year model so I will never get another 1st year model again. Fuel economy is bad (I live in CA with fuel prices pretty high) but it is as advertised with 13 city/19 hwy. I thought this car would be staying with me for a long time but after only 3 years owning it I am about to throw in the towel and look elsewhere for a similar model with a better service record."
