So upon taking a look at an old caliper bolt I had to replace before because the old one rusted off (had replaced both rear calipers/rotors/pads). I wanted to further inspect anymore rust that the only previous owner clearly didn't manage to say much about. (Not even MB Dealership and multiple same shop inspections noted any of this). I'm UPSET, to say the least.

The pictures you'll see obviously highlight the carnage and corruption that is the makeup of my sub-frame and suspension components. This is complete and udder Mercedes-Crime. I'm actually having thoughts of selling her after learning and putting a lot of effort into making her drive like brand-new. But this seems like a job I cannot continue with having the car. Any thoughts or suggestions as to what my options are next (even the jokes) are greatly appreciated. I'm more sad about this car than any break-up could be haha.

TBH I do not see anything other than normal surface rust (unless I am missing something:frown:) nothing that (to my eye) can not be improved by a good wire brushing and painting or wax oiling, preferably both.

But I am happy to be corrected :grin:

Rusting bodywork tends to see off more 170s than anything else, because it's expensive to fix. I'd take that car for a comprehensive structural inspection (in UK we have compulsory annual MOT tests which covers the under-body) and decide what to do after that. As others have said, if it's surface rust, it can be dealt with very easily.

Hi,

Considering it's age and as has already been said, your Car looks fine to me, just needs a little TLC to stop things worsening.

Clear Waxoyl and many Cans of Aerosol Grease are your friends, you learn this if like me you live in NW Highlands surrounded by Seawater, and Salty Rain plus the constant Brine that they spray all over our roads in winter ...............

My R170 and the W220 (which gets a little more winter use, as that has been completely stripped down underneath, behind wheel arch liners, inside doors etc etc and fully treated now), they rarely get driven it the winter, like once a week on a fine dry Day just to blow the cobwebs and keep the discs etc clean.

Pressure washing underside helps in Salty areas, under Wheel arches etc, when I buy a Car I do not buy a local Car, middle England is best for a rust free example :grin:

HTH, Cheers Dave

Thank you all SO much for the small tips. I'll take some more time into looking into the severity of the rust damage. If it's not all bad, I'm going to have to consider replacing suspension components then since they're basically attached with the rust as well. Cheers 0:)

That's not rust, that's patina. ;)

Rust you can see usually isn't the stuff to worry about, at least on bolts. If you can see it, water will drip off and it will dry. Areas that trap water have the worst problems.

I would point it out to my mechanic, but ultimately rely on their judgement.

As others have stated, it's not the end of the world, but I more than understand your discontent. This is the big reason why my SLK is from the west coast, to avoid things like this. I've brought back subframes that look much worse than that, it does take a bit of time with a wire brush/wire wheels. After that, POR15 is your BEST friend! POR15 is pretty nuclear stuff, but for those of us in the rust belt it's a must-have. Follow the instructions to the letter, and you'll never have to worry about the subframe rusting ever again.
