Hello.

Quick question. What parts of the W212 are of aluminum? I know the trunk lid is.
I want to know (and hope) all four fenders are made out if aluminum too.

Thanks!

not my chassis, it's old fashioned rusty steel I believe besides front sub-frame.
Engine/tranny are made of an allow of Aluminum with magnesium, manganese.

2014 facelift.
Bonnet/hood = ALU
Rear Trunk = ALU

Front fenders = ALU, only the flat outside fender. The strut mount tower is steel.

I meant this one as : the flat outside fender.

Take a magnet and test

Thanks for the replies! I was looking for a magnet, but didn't have any. I have a special fear of the "rust ghost" after owning a W208 CLK, and I am particularly afraid of rust in the wheel arch area. I live in Oslo, the capital of Norway and they salt the road like it's no tomorrow here in the winter. I curse every time I see the big vehicles spit out their salt. Going to get the car sprayed with lanolin oil this month.

I feel you my man.
Albeit me now snow and salt, I have a small Toyota I used to wade into salty high tide sea water at a fishing port, onlyc 30cm high but my car then rust at the rear inner fender

Did you ever find a magnet? Have you checked Amazon? Maybe Hjem Depot?

Thanks for the answers! Will buy a magnet in the next couple of days. Do any of you know how prone the W212 is to rust in general? Cant't wait to get it sprayed with lanolin oil on Friday. 95% of what I have read about lanolin oil is positive.

"after owning a W208 CLK, and I am particularly afraid of rust in the wheel arch area."
Those are especially bad years for MB and rust. Fortunately, I think they learned and the later models, ie after 2005, are better. I live in the salt happy Midwest of the U.S. and have yet to see a rusty Merc. My 2011 has spent its entire life in salt states and it looks good. What you do need to watch are the brake lines for the rear and rear subframe corrosion. Ps- say hi to Hanna😂

Yes, the W210 era was a disaster for Mercedes. What's sad is that the cars are bulletproof, but the rust kill them if they are not driven in very dry climates. I can see some pretty bad W211's here too, but some seems pretty good. It's weird. You know a Hanna from Norway?

I have owned both my 212's since new, I live in the snow belt, we get 100 plus inches a year and the salt that goes with it, I have zero rust on the outside, but my brake lines, dust shields on rear brakes rusted through and had to be replaced, so far my rear subframe is rusty but no holes yet.
