Mercedes-Benz C-Class - Build quality (rust) on the Mercedes C class Range - double_tap_that

Having recently bought a late 2001 (november) 51plate Mercedes C class estate, I am suprised of how much rust is appearing on the car, I bought it because of the space, history, and quality of the car itself, That and it being in an unusual dark graphite metalic colour (which i like very much), BUT being over ten years old, i didnt expect a mint car for under a grand.

I have read honest johns reviews and apparantly MB offered a warranty over corrosion as the bodies were all gavalanized?.

So my question is..

Are MB liable if i take my car in and ask them to rectify the rust problems, these are..

1. tailgate, just under the registration plate.

2. Blister on lower drivers door.

3. Front passenger wheel arch

4. Rear quarter panel arch

Its bubbling, not holed, but if its something that was originally guaranteed not to happen, have i a right to request repairs etc?

Not a chance without full dealer service history and even then I believe the get out clause is corrosion from the inside out.

Edit: It's also well over 10 years old.

2001? That's 13 years old, banger territory, caveat emptor.

Its 12 years old, Not quite " well over".

For a car that someone bought originally for 24k, thinking they got warrenty over rust problems from a quality company, its not really worth its weight in salt is it, so to speak!

Reality is, why buy new?

Thanks anyway guys

Not a hope in hell of MB being even slightly interested i'm afraid, , good old fashioned regular anti rust treatment inside and underbody, from new preferably, plus treating rust as it breaks out is the only way to keep it at bay.

It doesn't help that the vast majority of car buyers haven't a clue about keeping salt at bay underneath, and care less, very few new/nearly new car buyers keep them long term and even fewer have any idea about rust prevention.

Could you tell me how I should prevent rust, please?

Just to update the no hopers brigade, I spoke to MB in Plymouth and are willing to take the vehicle in and using a camera? which shows if the paint is genuine MB and not been in an accident, They are willing to look at the possibilities at going through a corrosion claim, So really, age has nothing to do with it, if a company at the time of production, gives you a corrosion warrenty, then by law, they have to stand by it.

If it leads to nothing then at least i tried and MB offered to take the car in and not totally dismiss the whole idea by saying, "Its an old car, what do you expect" attitude.

I will let you know what the outcome if any!

Every spring, after you have driven through several equinox rainstorms to rinse off the salt, go under the car with a wire brush and prepare every corroded-looking bit of metal for a coat of your favourite protective paint. Or just paint old engine oil on them.

Also, clean and grease the brake pipes - they are a favourite MoT failure if there is even a bit of corrosion near where they enter the caliper.

Also, try not to slam the doors - the bottom of the driver's door is probably the first place for rot to appear, so attack it with a screwdriver, ku-rust and touch-up paint as soon as it does.

Better still, buy an aluminium car.

Better still, buy an aluminium car.

Ever looked at old Land Rovers, Discoveries and even range Rovers. The corrode better than just about any other car on the road.

For those competent, rather than just venting, the LR rust phenomenon is caused by the fact that they have/had steel chassis with aluminium panels. Usually rust occurred in the chassis or on hinges, etc or where steel and aluminium met.

As will happen with virtually any connection between two different metals.

A better comparison would be something like the Audi A8, or the old Audi A2. Entirely Aluminium body, rather than steel chassis.

I am not "venting", I am just stating an obvious fact and I am fully aware of why it happens. But it does not excuse Land Rover from the fact that they sold expensive vehicles that corroded as bad (or worse) than anything else on the road.

If they had sold vehicles that were well built they would not have been overtaken by Toyota, Nissan etc. etc in the 4 x 4 market.

Mercedes-Benz C-Class - Build quality (rust) on the Mercedes C class Range - RobJP

Yup. Utterly overtaken. The defender still has a waiting list (as it has done since about 2006, recession and all.

All the other LR products, as you say. Utterly overtaken by those others, beaten into the dust.The Freelander, Evoque, Discovery, RR sport, RR ... none of them being sold, obviously. The others are patently so much better.

And before you come back at me with 'that's marketing' ... then the argument in return has to be that Toyota, et al. can't do marketing at all well. After all, if their products are so much better, then marketing should be the easiest job on the planet.

Or maybe you've been suckered into believing that their products are so much better, and everyone else has got it right ?

Mercedes-Benz C-Class - Build quality (rust) on the Mercedes C class Range - skidpan

Not just talking about the UK market, I am talking about the world market.

Marketing for all 4 x 4's in this country has been a masterpiece of persuading people they need a big heavy 4 x 4 to take the kids 3 miles to school.

And for the record personally I am no Toyota lover. The reception I have received from the dealers on the 2 occations I have looked at buying one of their cars put me off (I tried 3 dealers and all were as bad). Have had 3 Nissans and all have been great.

Going off the topic a wee bit, I was on a beach years ago where some chap with his boat came ashore, he walked off to get his bmw x5, with trailor to winch his boat on to go home , well (lol) he got stuck in the sand and the tide was coming in, and he didnt even have the trailor attached to weigh him down.

Anyway, along came this banger of a 1970 land rover( not sure of the mode)l but he managed not only to tow the bmw off the beach, but also he attached the trailor with boat as well!

The BMW driver just look so embarrassed and Pee d off i never seen him again.

Think we went off and bought a landy that could actually do what it says on the tin!

All true. But utility comes in many forms.

The Defender is a special case, and many of its adherents admit an irrational affection for it. I've owned one, and been in and out of one as a passenger this weekend. The owner concedes that it's noisy, slow, the aircon consists of some flaps under the windscreen, and that it leaks when it rains. He just likes it, but it's nothing to do with build quality, comfort, and reliability.

I have also been in a newish (Feb I think) Discovery. Beautiful car. About 30-32mpg and very handy with a heavy trailer full of village show paraphernalia. The interior is lovely, like my Outlander it has black leather seats but the Discovery is in a different class. It's the third one the owner has had. The first he ran for three years, didn't see the point in changing it, so kept in for a fourth in which it cost quite a bit in repairs. The second was already having problems at 3 years so he swapped it for a third. He also just likes them, because they are so capable, comfortable and do what he wants. And actually the reliability is probably at least as good as the average 'executive' car.

As for the Evoque - yes, it's marketing. They have played the heritage card well, but they have been true to the brand - all LR products do the business off road and as long as they do that, then the brand will sell them even if the buyers never take them near a field or green lane.

If reliability was what sold cars then there'd be no Audi & BMW, and not many VW/Seat/Skodas either.

Have owned 4 VW's. In over 250,000 miles I replaced the exhaust on one (after 90,000 miles), the exhaust rear box on another (after 60,000 miles), a rear brake caliper on one (after 100,000 miles) and one battery (after 95,000 miles). In my books that is very good.

Had a BMW, in 5 years it was 100% reliable.

Currently have a Seat, its absolutely spot on.

Happy to hear it. I hope I am as lucky with our new 1.2TSI DSG Roomster.

The best way is to ring around local classic car specialists to find one that will pressure spray an anti-corrosion agent into the sills, chassis box sections, doors etc using a powered compressor and various wands to get inside the various drain holes etc. The really damaging corrosion comes from the inside out.

I had this done on my old MGB back in the 90s, the garage used a mix of Waxoyl and cheap fresh engine oil. Horrible stuff but when properly atomised using a compressor and spray wand, it covers and clings to all surfaces.

It cost me £75, 20 years back. The car was still in excellent condition when I sold it, and is still registered as being on the road ...

Spot on. My 34yr old Ziebarted TR7 is completely unrestored apart from a respray about 20yrs ago; still has its original sills. And by 'all aluminium' I did indeed mean cars like my recently acquired eight year old A8 which with probably last longer than me. Installing a battery and wireloom in a machine consisting of different types of metal joined to each other is a recipe for corrosion.
