Well they also say: "If it not rust it's not a real MB" hahaha
But the newer models don't really have those problems. My ex W203 and W220 had some starting rust spots but nothing special, when you thread the car good and keep it as clean as possible the rust won't come that hard.
My W211 is allready one (almost two) weeks in front of my door... It's looks like a Citroën... The back of the care has problems with the airmatic ball (it's leaking) so it goes to the garage after christmas to get it fixed. C209 is doing his job.
But I must admit last week (and I think it will take a bit longer) I am cheating a bit since I am driving a Audi A6 :undecided: nothing really special a 2.0TDI it has 150 horsepowers, again nothing special but hey it doesn't cost me much and has now 2500km on board so it's basicly new. I think I will drive it until next week or something since there's a buyer for it but he needs to do his work for a couple of days this weekend since I am going to do a lot of driving need to go to Belgium and Germany think it will make 700 to 1000km's in two days so hahahaha rather do it with a "demo" car from the company than with one of the Benzes hahahaha
