    Finally I took delivery yesterday of my 230 with C1, C4 and C5. The car is a joy to drive and I echo all of the fabulous comments made here by those lucky enough to know this car sooner than me. I have only one problem which is with the sunroof (no it has not fallen off). I have raised this issue in the past (based on my test drives) but have not received many comments. With the sunroof open, there is a very evident air fluttering over the windscreen and open glass that produces ear pain, a feeling akin to descending in an aircraft. It comes and goes, but is present most of the time. It gets so bad that my passengers request that the roof be closed (so what's the purpose of that wonderful panoramic roof?). I know that MB is redesigning the windscreen for 2003. Has anyone else had this problem and if so, how has your dealer addressed it? I really want to be able to go to the dealer with some information (and I really want to be able to enjoy my panoramic roof open).

    Sunroof resonation is a very common occurrence on many vehicles. Both of my wife's last two cars have had it, and my (older) 911 has it as well.

    The general fix is to open one, not both, of the side windows a bit.

    Cira, How do you know the windscreen is being redesigned for 2003?

    I, like others, have noticed buffeting around 40-50MPH. I can't speak for my passengers (haven't had any in the back with roof open) but, the buffeting hasn't caused me physical pain.

    I can't imagine the dealer coming up with a fix in this case. They'll probably tell you what Huntzinger said: It's a sunroof- wind comes in and resonates. Close the roof or open a window.

    aavlis, see my post #888 for a list of 2003 changes. Thanks to you and Huntzinger for the advice. I was hoping there were something less practical and more technical I could do to address the problem - I just like the windows up. Anyway, still enjoying the ride!

    In light of compelling evidence to support your claims, I got the go ahead from management to delete the posts in question. For the sake of continuity, I also deleted a number of messages that were in direct response to these posts. That's for the heads up.

    And now back to the subject of the Mercedes-Benz C230. Happy motoring!

    I have some buffeting in my car, which isn't a C230. The sunroof has two opening positions. The first stops about 3 inches before the roof is completely open. If you push the button again it opens the rest of the way. With the roof fully open their is a big increase in the amount of buffeting and you really notice it. With the roof stopped in the first position you really don't notice any buffeting until you get into 60 MPH+ range.

    I don't remember if you could control how far the sunroof opens when I drove the C230. You might try not opening the roof all the way and see if it helps. I loved the C230 sunroof when I drove the car, I think there will be some buffeting with just about any car with a sunroof open at some point.

    Cira, I've seen that list posted elsewhere and my opinion is that we won't see these changes 2003. it reads more like someone's wishlist rather than reliable info. I find it hard to believe MB would make that many changes after just one year in production. I'd be willing to bet that those changes will happen incrementally over the life span of the car (typically 6 years?) if at all. In the case of the roof design, I would think that MB tested the design and optimized it before it's production release. A redesign after only one year would mean to me that they just slapped the design toghether for the 2002 and released it without testing it at highway speed. Highly unlikely. Ditto for the seats and steering wheel: I wouldn't hold my breath...

    I've only got 350 miles on my car and the past two times I've started it in the morning, I'm met with this high pitch whine that goes away after about 15 minutes. Customer service told me that as cars get older you'll hear new noises. Finding that unacceptable I called Carol at 800-FOR-MERCEDES and luckily she's got one of these and told me to take it in for service and if they all do it at some point, line a couple up in the lot and let me hear it on them. Got an appointment next week.

    Thank you. That is fair.

    I have found a coupe with the color, interior, and other options I want but it does not have a sunroof. My last car had a sunroof but I seldom used it except to crack it open for ventilation. I don't like the sun beating down on me and when the roof was open it was quite noisy. You don't really see out of it if you sit in the front except when the car is stopped at rest on occasion. It's nice for backseat passengers but I almost never carry backseat passengers. The color of the coupe is white and I like the exterior look of the white hard top better than with the black sunroof. The sunroof seems to be a big selling point for this car and my guess is reselling will be harder without it. So, what do you think, am I crazy to buy a hard top especially if I plan to sell it in a coupe of years?

    You're welcome. Btw, just noticed my typo above; I meant to say "thanks" for the heads up! ;-)

    buy the car that YOU want, and not to worry about what may happen with a possible sale years down the road. If you really don't want a sunroof, don't get one. There are plenty of people who share your misguided opinion of not liking them :-). It really is a very nice sunroof, though!

    Also, don't discount the rain sensing wiper aspect of the package - it's a great feature all on its own. Not worth the cost of thd C2 package by itself, but it's a nice throw-in in its own right.

    Revka, glad that you were able to remove the offender.

    Chipman - I bought a C230K with no sunroof; I am very pleased with it and do not regret missing out on the admittedly very slick device. Though I have not seen any failure issues posted here, I have read complaints about buffeting when using the sun roof. I don't have that problem. I prefer the look of my car too (with the roof panel finished in paint to match the rest of the car) to the sun roof closed look of the cars whose glass top contrasts with the finish on the rest of the car. It is a matter of choice, of course, but I rarely have used sunroofs on previous cars so standard car was my preference.
  • ciracira Posts: 37
    Tommyp13 is right, buy what you like. If you won't use it, don't buy it. I am a sunroof freak. I switch my heated seat on in the winter and open the roof - I just love fresh air. But if that is not you, don't get it just because you think it goes with the car. If it helps, I will tell you that the car is very quiet with the roof either open or closed. I am one who complained about the buffeting, but not about noise. Also, with the sunshade open and the roof closed, the car is a lot more airy inside, and the tinted glass keeps the sun from bothering you 90% of the time. So from a functional perspective, I don't think you will be unhappy if you purchase a 230 with the sunroof "for resale purposes." But if I didn't like the way the car looked with the sunroof and I wasn't planning on opening it, I wouldn't get it.

    get what you want! Don't buy the car for someone else 5 years down the road.

    I decided to go with the sunroof. Cira's comment "(with)...the sunshade open and the roof closed, the car is a lot more airy inside" was a deciding factor that I had not considered. I also like the fact that I can vent the car and I know I'll get some pleasure opening the roof during the summertime as well. I still say the all white coupe looks sharper but after weighing all the factors the sunroof gets the nod.

    Thanks for the input everyone!

    I was wondering if anyone has installed an XM radio in their C230 yet. I was thinking of having one installed as an add on with the FM Modulator. I am not sure where to have the display installed though. Any thoughts/suggestions....

    Congrats on your new car! I don't believe I've seen an Alabaster White C Coupe Yet!

    Good luck Chipman. I know you are going to love the sunroof (open or closed) and personally I think that the white and black contrast will only add to the pleasing look of the car. Enjoy it, I know I am. I picked mine up exactly a week ago at this hour and I am loving it (brilliant silver with black leather). I take the long way to and from work everyday!

    pablo12- Go to the C-Class(203) forum at and do a search for poster name "Buddha" (The search function is on the right-hand side at bottom of screen). Buddha talks about his installation and posted a pix.

    Good luck

    I test-drove a MB C230 last weekend. The salesman, who seemed to be a decent fellow, called today to say they're having a sale ('very aggressive pricing') this weekend. This might be the case at other dealerships. I don't want to be here advertising, but you can email me for details if you want, because I normally don't haunt this board.

    After procrastinating for months, I ordered my C230 on 4/9/02.

    After the test drive and the decision to buy, my dealer went to her printouts to see what was coming in. Her 2003 list (which starts in June) did NOT include C230s. Instead, C190s noted as "(new engine)" were on the list. She said that MBUSA had apparently changed the engine to keep costs in line.

    I was able to order one of the few C230s to be produced in May, but almost waited too long.

    Has anyone else heard this? If it is true, and you have been waiting, don't wait too long.

    ...are indeed coming for next year. The new, all-aluminum 4 cyl engine has been documented on the MBSPY website...long article that you can read there.


    Look for the M271 Engine Series article - Misc near the bottom of the index page.

    With supercharging, direct injection, balance shafts, and [I think] ULEV certification, these engines should be less thirsty and about the same in power for each of the older engines that they replace in the lineup.

    Since the Coupe is the only MB currently sold here with a 4 cyl, and since there will no doubt be only the one engine choice for us, all of the verbiage about the rest of what the new family of 4 cyls will offer is beside the point.

    Power and torque will be VERY slightly less than the current 2.3, but fuel consumption, smoothness, quiet, and emissions all favor the new engine. [Long story, but this should have happened about 5 years ago, however MB botched an earlier attempt to replace all of the old-gen 4s in the lineup...they are ready now to get on with it.]

    Just like the majority of posters to this board, I am a very happy owner of a C230. I purchased this car from the MB dealer in Greensville, SC, in Nov 01, and was treated like a king by them.

    I was very impressed with the dealer, with the Mercedes mystic, their leading-edge safety and service reputation, and with my road testing of the car. Although I was in the market for a BMW 3 series at the time, I was shying away from BMW after reading of all the problems owners were suffering from their electrical and mechanical problems during the last year. I especially felt that BMW in general, and the dealers specifically, were less than concerned with their customers problems then they should have been. Although the 3 Series drives/performs the best of all coupes in this category, I personally felt that the C230 with the 6 speed was close behind in fun to drive and road feel; and at $5k-10k less in price than the 3-Series, was the best choice. And I much preferred it to the WRX and RSX-Type S in ride, quality and comfort too. Just my two cents.

    I have a 1994 C180 which has a glass sunroof. At the moment it has trouble sliding back and forth, a wee bit slow with some grinding noise like the motor struggling. It still opens and closes fully though, but it doesn't tilt up at all. Have been told it needs total overhaul and the pack costs A$1200 incl. labour to do it. Anybody out there having this problem yet? Car has done 180,000kms, maybe its time for some serious repair business! Was told the main culprit is the 2 sides lifting mechanism which is a complex of metal hinges and slides. The big cost is the labour as it takes 4 to 5 hours work. Also needs other related components which are not reusable, but required in this overhaul. Pray the motor is still alive after all this surgery!!!

    I am waiting for delivery on a black C230. I am wondering if the MB mud flap option will help in keeping the car clean. Has anyone bought them? Are there any pictures that show them?
  • jjpeterjjpeter Posts: 230
    Yeah bmoody, I bought and installed them. It does prevent the wash from the front wheels from getting on the sides of the doors. No pics but one thing I don't like about them is that they don't fit the under side contour of the car perfectly. There is a small gap in the center, about a 1/4". Installing them was kind of tricky, I didn't take the wheels off, and that might have made the install easier. If you want to avoid the hassle, have your dealer put them on.
  • Although it has been noted as having "VERY" slightly less power and torque, the numbers I read do not quite match that. Remember the current iteration with the 2.3 litre Kompressor can be tweeked all the way up to approx 230hp. So, even though the 2.3 is set around 192hp, the new engine is slated to get maybe 180hp or possibly something less in its final production (i.e. 170hp). So, 10% less hp with 5% greater mpg is not that big of a deal. Also, I will believe the new engine is quieter when I actually hear it. It is the supercharger that is the main noise you hear from the 2.3l. The new engine will also be supercharged, so I am not convinced it will be any quieter. As a side comment, I love the sound! So, make your own deicision, but I would not wait for the 2003 just because you think it is rumoured to be "better". The 2.3l will likely continue on in the SLK and in C Coupes in Europe. I think the new engine is simply a cheaper version to keep the entry price in the US near 25K. In my mind, that is a bad excuse to wait for the 2003.
