I want to buy a used one it has 22,000 miles on it certified pre-owned from the MB dealer are there any known complaints or problems with this model?

any mercedes is a dependable car.

i have a 2006 c180k. and its awesome.

my mom has a 2007 slk300.

we both got our cars from mercedes directly and we have had no problem with the dealership or the cars themselves.

she loves her car and has never said a bad thing about it.

if it only has 22000miles and is merc certified then id say go for it. they are great cars that last and wont let you down.

I just traded an 06 SLK350 in diamond silver in. It was a joy to drive and gave me no problems for the entire couple of years that I owned it. The only issue that I can remember was when I first got it, the roof was not exactly flush with the window so it was making a noise. As soon as the problem was noticed the dealership took care of it right away, even pushed me to the front of the loaner line.

I'd give the car a little more credit being that its a certified pre-owned as well, since there is some sort of inspection and warranty associated with it. Good luck, and have fun driving!

i really don't know ask an expert

No.there are beautiful. You will go to the representance all the time if something is wrong.No street mechanical.
