I myself was debating on getting a head gasket done. I have 94 C280 with 93,000 miles. Its definitely leaking but cant find the leak and could be towards the back of the engine and cant see it. I was quoted around $1500 for a head gasket job. I was wondering if getting a head gasket done with this kind of mileage is worth it. I plan to keep the car for at least 3 years.

Any advice will help my decision. Thanks.
