New (almost) 2013 C300 Sport owner in New England
I plan to make this my summer car and use an older but well maintained Subaru Forester for a winter car.
From all my research, this seems to fornone of th most reliable years/models for Mercedes. I know this is introductions but I also have some general questions.
1. I've already looked it over and took it for a test drive. I didnt want to kick the tires too much since it seems like a great deal. Is there anything I should have looked harder at other than typical things you can see and feel driving it?
2. Honestly my days of doing massive amounts of work to cars are behind me. I can do things like change the oil and filters, spark plugs, disc brakes, etc etc etc. Will i be able to continue that in this? Keeping in mind I have no lift.
3. Is there any maintenance around these miles i shluld be looking at? I read the previous years a transmission service would be due but these ones can wait until 80k miles.

2. If this vehicle has a dipstick, you can extract the engine oil, the filter is on the top as well if that is the case.
3. Many fluids, transmission, etc.




Is it a PZEV spec? If so that means the car has an extended 15yr/150,000 mile warranty on anything to do with emissions. Covers things like spark plugs, air intake, exhaust, purge valve, fuel filter etc. My exhaust manifold developed a leak and needed to replace it, its such a pain to do I ended up paying thousands for the MB dealer to replace it, the kicker is it was just over the 150,000 miles or else it would have been covered.
Based on the cars age I would closely inspect the rear axle carrier (subframe) for rust which is a known issue with MB's, fortunately MB will replace it for free. But they wont pay for rusted brake lines which is another known issue, i had to replace a severely rusted section last year and will be replacing another section once it gets warmer to work on the car.
For maintenance I do all the work myself minus the exhaust manifold. C300 is pretty easy to work on. There should be a Maintenance Manual in the glove box with the Operators Manual, just go thru that and make sure all the recommended service is complete based on age/mileage.
You should be fine for everything else because of the low mileage. Should just be normal Service A and Service B for awhile. From my experience once the car hits 100,000 miles then things start going like suspension, bushings, maybe even starter and alternator.
Do you have a Mercedes specific OBD scanner, its a good idea to check the computer for any fault codes.

To fill the oil I just dump it in the oil filter housing before putting the filter back in.

I talked to the garage he took it too, pretty reputable place. They did any maintenance on it and went over it when he bought the car. And just a few months ago they installed new mufflers on it. They have the originals too. The garage said they never saw anything wrong when performing the work they did.
Same question about the WSL issue. Is thst something thst just will eventuallt happen?
