Typically, I'm not a big fan of extended warranties. I see it as Mercedes-Benz taking a gamble that your car will require less than $1200 of service in the next two years. Assuming they're not out to lose money (which they aren't), you'll probably come out ahead budgeting your money and skipping the warranty.

At the same time, however, we all know how expensive MB repairs can be. If there are a lot of known issues with the C230, it may be worthwhile to spend the extra money now for added peace of mind later. I did own one car, a 1994 Saturn, where the extended warranty definitely paid for itself. They made the purchase decision easy, though, with a deal that would refund the cost of the warranty when it expired if I never had to use it. I skipped the added coverage on every car I've had since, and I've never had a problem. Like I said, it can be a gamble either way...
