I have a new 2005 C230. From the moment I drove it out of the dealership lot, I noticed it pulled to the right. I have driven it for about 1000 miles now and tried a range of roads. The more crowned the road, the harder it pulls to the right. However, even on what appears to be virtually flat highway or road, it still pulls right. I took it back in and had them verify the alignment, tire pressure, etc. The dealer told me that the stock cars from the factory are not set up to compensate for road crown, and thus, they typically will pull to the right. They installed under warranty a camber bolt kit to slightly adjust the camber to compensate for road crown. It's a little better, but it still drifts to the right. It seems to me this is tricky since different roads will pull it harder...so there is no optimal point. They also said that the low profile tires have an aggressive tread and that this amplifies the situation. My question is: why does this really happen on the C230? I owned an E320 and it went straight, even on a road with crown. We have a Honda SUV. It goes straight even on a road with crown. What am I missing here? Why would this car pull to the right. As an aside, they loaned me another C230 (brand new) while mine was in the shop. That one too pulled to the right. Is there something in the suspension of the C230 that's designed to hug the road and follow the slope??? It's annoying yet I have a feeling they may never really be able to fix it and I may just have to live with it and get used to it. Anyone else have this experience or understand why this is happening?
